ORDER

1. INTRODUCTION

In July 2024, Plaintiff Ryan P. O‘Boyle (“O‘Boyle“) sued Defendants Mark Sheremeta (“Sheremeta“), Ana Romero-Perez (“Romero-Perez“), Kristopher Maduscha (“Maduscha“), Nash Dathe (“Dathe“), Nathan Locicero (“Locicero“), and Shawn Humitz (“Humitz“) (together, “Defendants“), members of the Milwaukee Police Department (“MPD“), for monetary damages pursuant to 42 U.S.C. § 1983 based on various alleged constitutional violations surrounding his arrest in November 2022, as well as two state law claims. Although the docket reflects pending cross-motions for summary judgment, ECF Nos. 80 and 89, because O‘Boyle is proceeding pro se and did not file an opposition brief to Defendants’ motion for summary judgment, the Court will construe O‘Boyle‘s motion for summary judgment as his opposition brief to the Defendants’ motion. The Court does so to O‘Boyle‘s benefit, because construing his filing as an opposition brief requires the Court to draw all reasonable inferences in O‘Boyle‘s favor as the nonmoving party. See infra Section 2. Even when doing so, the Court finds no genuine issues of material fact that would enable any of O‘Boyle‘s federal law claims to proceed to trial. The Court will thus grant Defendants’ motion for summary judgment in part, to the extent it concerns the federal law claims, which will be dismissed with prejudice. Given the dismissal of all federal law claims, the Court declines to exercise supplemental jurisdiction over O‘Boyle‘s remaining state law claims, which will be dismissed without prejudice. With all claims addressed, this case will be dismissed.1

2. LEGAL STANDARD

Federal Rule of Civil Procedure 56 provides that a court “shall grant summary judgment if the movant shows that there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law.” FED. R. CIV. P. 56(a); see Boss v. Castro, 816 F.3d 910, 916 (7th Cir. 2016) (citing FED. R. CIV. P. 56(a) and Alexander v. Casino Queen, Inc., 739 F.3d 972, 98 (7th Cir. 2014)). A fact is “material” if it “might affect the outcome of the suit” under the applicable substantive law. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 248 (1986). A dispute of fact is “genuine” if “the evidence is such that a reasonable jury could return a verdict for the nonmoving party.” Id. (citing First Nat‘l Bank of Ariz. v. Cities Serv. Co., 391 U.S. 253 (1968)).

The Court construes all facts and reasonable inferences in the light most favorable to the non-movant. Bridge v. New Holland Logansport, Inc., 815 F.3d 356, 360 (7th Cir. 2016) (citing Burritt v. Ditlefsen, 807 F.3d 239, 248 (7th Cir. 2015)).

At summary judgment a court may not assess the credibility of witnesses, choose between competing inferences or balance the relative weight of conflicting evidence; it must view all the evidence in the record in the light most favorable to the non-moving party and resolve all factual disputes in favor of the non-moving party.

Abdullahi v. City of Madison, 423 F.3d 763, 773 (7th Cir. 2005) (citing Anderson, 477 U.S. at 255). Ultimately, “the non-movant need not match the movant witness for witness, nor persuade the court that h[is] case is convincing, []he need only come forward with appropriate evidence demonstrating that there is a pending dispute of material fact.” Waldridge v. Am. Hoeschst Corp., 24 F.3d 918, 921 (7th Cir. 1994) (collecting cases). But simply “denying a fact that has evidentiary support ‘does not transform it into a disputed issue of fact sufficient to survive a motion for summary judgment.‘” Uncommon, LLC v. Spigen, Inc., 305 F. Supp. 3d 825, 838 (N.D. Ill. 2018) (quoting Roberts v. Advocate Health Care, 119 F. Supp. 3d 852, 854 (N.D. Ill. 2015)).

3. FACTS2

3.1 Procedural Background

O‘Boyle is an adult resident of the State of Wisconsin. ECF No. 81 at 1. In 2012, O‘Boyle was convicted of Second-Degree Intentional Homicide (Attempt). State of Wisconsin v. Ryan Paul O‘Boyle, Case No. 2011CF3261 (Milwaukee Cnty. Cir. Ct. 2011), available at https://wcca.wicourts.gov/caseDetail.html?caseNo=2011CF003261&countyNo=40&mode=details (last visited Aug. 31, 2026) (“State Case“). He was sentenced to state prison for 8 years, followed by 5 years of extended supervision. Id., Sept. 28, 2012 docket entry. His extended supervision took place “by and within the custody and control of the Wisconsin Department of Corrections” (“DOC“). ECF No. 81 at 1 (citing WIS. STAT. § 302.113(8m)(a)). At the time of the events giving rise to this lawsuit, O‘Boyle was serving the extended supervision portion of that sentence. Id. at 1–2. However, following his arrest on November 24, 2022, O‘Boyle‘s term of extended supervision was revoked. Id. at 2. On April 24, 2023, the state court ordered that he be incarcerated for three years with custody credit from November 24, 2022 through April 24, 2023. Id.

In July 2024, O‘Boyle commenced this lawsuit. ECF No. 1. O‘Boyle‘s live claims include: (1) Fourth Amendment unlawful seizure/arrest; (2) Fourth Amendment unlawful entry to a residence; (3) excessive force; (4) Fourth Amendment unlawful post-seizure/arrest detention; (5) false imprisonment; and (6) failure to intervene. ECF No. 25 at 8–9; ECF No. 81 at 2. The operative complaint identifies six Milwaukee police officers—Sheremeta, Romero-Perez, Maduscha, Dathe, Locicero, and Humitz—as the alleged wrongdoers. Id. at 2–3.

3.2 Factual Background

3.2.1 The 911 Call and Subsequent Interaction with the Caller

At 12:46 a.m. on Thursday, November 24, 2022, Milwaukee emergency dispatch received a 911 call alleging that a battery had occurred earlier that night (on November 23, 2022). Id. at 4. At 12:55 a.m., Sheremeta and Romero-Perez were dispatched to an address on 5th Street to meet with the caller (the “Complaining Witness“). Id. Both officers were equipped with body-worn cameras and their subsequent conversations with the Complaining Witness were fairly and adequately recorded. Id. The Complaining Witness told Sheremeta and Romero-Perez that “she had gone out with O‘Boyle earlier that night,” “he had left her at the establishment but later returned (at her request) to drive her home,” “they had argued in his truck,” and that “O‘Boyle had tossed or forcibly pushed her out of the truck and driven away but later returned again and drove her home.” Id. The Complaining Witness further reported to Sheremeta and Romero-Perez that, after O‘Boyle shouted at her to get out of his truck and she refused, he put either one or both of his hands on her neck and squeezed, allegedly impeding her breathing. Id.

The Complaining Witness provided O‘Boyle‘s contact information and a recent photograph of him to the officers.3 Id. She also reported to officers that O‘Boyle was on parole, that he said he had guns in his basement,4 and that she “was scared for her life.” Id. at 4–5. Sheremeta took photos of the Complaining Witness‘s upper chest and neck depicting fresh red marks and superficial scratches below her clavicle/collarbone area. Id. at 5 (citing ECF No. 85-13). Although the Complaining Witness reported that O‘Boyle had pushed her from his truck and she fell hard on the concrete, she did not have any visible injury to her hands, arms, head or side. Id.

3.2.2 O‘Boyle‘s Arrest

O‘Boyle‘s mother, Kathleen O‘Boyle (“Kathleen“) owns a single-family residence at 4715 W. Howard Avenue, Greenfield, Wisconsin (hereinafter “4715“). Id. at 5. The Complaining Witness informed Sheremeta and Romero-Perez that O‘Boyle lived with his mother at 4715. Id. at 6. Sheremeta and Romero-Perez went to 4715 to locate O‘Boyle around 1:50 a.m. Id. at 6. Dathe, Locicero, and Humitz also responded to 4715 to provide backup. Id. Each of the Defendants wore body cameras that fairly and accurately recorded their activities on-site. Id.

After arriving, Sheremeta saw O‘Boyle‘s truck parked in the driveway behind 4715. Id. Sheremeta told Romero-Perez, Dathe, Locicero, and Humitz about O‘Boyle‘s prior conviction and supervision status and that, “supposedly, he‘[d] told [the Complaining Witness] . . . that he[] [had] guns in the house.” Id. (citing same). In reference to whether additional units were or were not still coming, Sheremeta stated his preference for “‘an extremely large display of force‘” to diminish the likelihood of a standoff.” Id.

At approximately 2:10 a.m., Sheremeta, Romero-Perez, Dathe, and Locicero (the “Entry Team“) approached the front door, knocked several times, and announced themselves as “Milwaukee Police.” Id. at 6–7. Each officer in the Entry Team wore a body camera that fairly and accurately recorded their activities on-site. Id. at 7 n.12. Humitz was present outside the residence but did not enter. Id. at 7. The Entry Team was positioning itself outside the front door, around 2:12 a.m., and Sheremeta told Romero-Perez: “swing that door and come over to the right – hold the door open to the right – hold the door open to the right so you‘re out of my way – out of my line of fire.” Id.

At 2:14 a.m. an exterior light came on, and before the door had opened, Sheremeta stated again: “Milwaukee Police.” Id. Kathleen opened the door and asked, “What‘s going on?” Id. Sheremeta replied, “Hi, is Ryan here?” Id. Kathleen replied “[Y]eah, what‘s going on?” Id. Sheremeta then asked, “Can you have him come to the door please5?” Id. (footnote added). Kathleen then turned back into the house and called out “Ryan?” Id. The Entry Team defendants were equipped with firearms and that the video footage produced in this case fairly and accurately depicts how those weapons were held throughout the events depicted. Id.

None of the Defendants explicitly asked Kathleen whether she consented to their entry. Id. The Entry Team, led by Sheremeta, followed her into the living room where Sheremeta asked for the first time whether O‘Boyle had access to firearms inside the house. Id. Then, Sheremeta called out “Ryan—Milwaukee Police, come out please!” Id. Within seconds, O‘Boyle appeared and was taken into custody. Id. When O‘Boyle came into view, Sheremeta ordered him to turn around, get on his knees, and put his hands on his head. Id. O‘Boyle complied. Id. At approximately 2:15 a.m., Locicero and Dathe approached O‘Boyle and secured his hands behind his back in handcuffs. Id. at 7–8. The parties agree that Sheremeta, Romero-Perez, Dathe, Locicero, and Humitz were inside 4715 when O‘Boyle was seized, and that Maduscha was not present at O‘Boyle‘s home. Id. at 3.

O‘Boyle does not allege any injury resulting from the way in which he was secured, only that the seizure itself was objectively unreasonable, i.e., excessive. Id. at 8.

3.2.3 The Events That Followed

At around 2:20 a.m., Officer Locicero loaded O‘Boyle into the police car for transport to District 6. Id.; see also ECF No. 85-19 at 4:45-5:30 and 85-20 at 8:45-10:59. O‘Boyle does not claim any physical injury in connection with how he was loaded for transport. ECF No. 81 at 8. O‘Boyle was transported to District 6 and removed from the vehicle without incident. Id. At 3:06 a.m., Sheremeta contacted O‘Boyle‘s probation officer and requested a “probation warrant,” presumably related to O‘Boyle‘s violation of conditions of his supervised release.6 Id. MPD District 6 received a hold from the DOC around 3:07 a.m. Id. (internal quotation marks omitted).

O‘Boyle was booked; then, shortly after 5 a.m., Sheremeta and Romero-Perez conducted a custodial interview of O‘Boyle at District 6. Id. O‘Boyle‘s failure-to-intervene claim against Maduscha arises from the interaction he had with Maduscha either immediately before the interview or shortly after when he returned to his cell. Id. O‘Boyle alleges that he told Maduscha his arrest was unconstitutional and Maduscha should have released him or caused him to be released. Id. at 8–9. O‘Boyle agrees that the officers did not force him to speak with them, but states that he was nonetheless compelled to do so because of his status as a person on extended supervision. Id. at 9. O‘Boyle has remained in custody since his arrest. Id. at 9–10.

4. ANALYSIS

Defendants move for summary judgment on all six of O‘Boyle‘s claims.7 ECF No. 80. The Court begins with its probable cause analysis (as it is pertinent to several claims; namely, the unlawful entry, unlawful arrest, and the federal false imprisonment claims). It will then address the merits of O‘Boyle‘s unlawful entry claim, his unlawful arrest claim, his federal false imprisonment claim, and his post-seizure arrest/detention claim. The Court will lastly address O‘Boyle‘s federal failure to intervene claim, before concluding with a discussion of his corresponding state law claims (his false imprisonment and failure to intervene claims under Wisconsin law).

4.1 Probable Cause8

“An officer has probable cause to arrest ‘if the totality of the facts and circumstances known to the officer at the time of the arrest would warrant a reasonable, prudent person in believing that the arrestee had committed, was committing, or was about to commit a crime.‘” Kovacic v. Ruechel, No. 23-C-642, 2025 WL 2709522, at *5 (E.D. Wis. Sept. 23, 2025) (quoting Abbott v. Sangamon County, 705 F.3d 706, 714 (7th Cir. 2013) and citing Michigan v. DeFillippo, 443 U.S. 31, 37 (1979)). “The inquiry is a ‘purely objective’ one and it does not deal in ‘hard certainties’ but rather ‘probabilities.‘‘” Id. (quoting Abbott, 705 F.3d at 714).

In this case, the parties agree that there was a 911 call by the Complaining Witness herself reporting a battery earlier that night, ECF No. 81 at 4, which is a crime. See WIS. STAT. § 940.19(1). Courts “presume the reliability of an emergency 911 call” such as this. United States v. Hopewell, 498 F. App‘x 609, 611 (7th Cir. 2012) (citing United States v. Drake, 456 F.3d 771, 774–75 (7th Cir. 2006) and United States v. Hampton, 585 F.3d 1033, 1038–39 (7th Cir. 2009)). That presumption remains intact as long as the call contains “sufficient indicia of reliability.” Gray v. City of Evanston, No. 23-CV-1931, 2024 WL3495009, at *5 (N.D. Ill. July 22, 2024) (quoting Navarette v. California, 572 U.S. 393, 397 (2014)). When Sheremeta and Romero-Perez followed up on the 911 phone call and met with the Complaining Witness (who the parties agree had gone out with O‘Boyle earlier that night, ECF No. 81 at 4) to learn her narrative of events, they saw and took photos showing that “her neck was visibly red and scratched.” ECF No. 87 at 13 (citing ECF No. 81 at 5); see also ECF No. 85-13 (photos of Complaining Witness on November 24, 2022). These observations were consistent with her reporting to the 911 dispatcher and later that day to Sheremeta and Romero-Perez that O‘Boyle had “put either one or both of his hands on [the Complaining Witness‘s] neck and squeezed[,] allegedly impeding her breathing.” ECF No. 81 at 4 (citing ECF Nos. 85-15 and 85-16).

This evidence refutes O‘Boyle‘s argument that Defendants lacked probable cause here because the Complaining Witness was intoxicated at the time she provided a statement to Sheremeta and Romero-Perez. ECF No. 89 at 2. Because Sheremeta and Romero-Perez‘s observations (and the photos of those) corroborate the Complaining Witness‘s firsthand account that O‘Boyle committed battery against her, considering the totality of the circumstances, it is apparent that officers had the indicia of reliability they needed to uphold the presumption of reliability from the original 911 call. See United States v. Orr, 969 F.3d 732, 736 (7th Cir. 2020) (noting that the “(1) degree of police corroboration; (2) the informant‘s firsthand knowledge; [and] (3) the detail provided” are factors in deciding an informant‘s reliability (quoting United States v. Haynes, 882 F.3d 662, 665 (7th Cir. 2018))). While the Court appreciates that O‘Boyle may be correct in noting that the Complaining Witness has no “cuts, marks, scrapes, bruises or abrasions on her side, head, arms, legs . . . to substantiate her allegations of being pushed from [O‘Boyle]‘s truck,” ECF No. 89 at 2, none of this pertains to whether there was evidence that he had committed a battery (strangulation), which is at the heart of this analysis.9 See Hartfield v. Richardson, 94 F.3d 647 (Table), 1996 WL 453224, at *1 (7th Cir. Aug. 8, 1996) (“Hatfield provided no reasons, other than his son-in-law‘s lack of visible injuries and the fact that the charges against him proved to be untenable, why it was not reasonable for defendants to believe the complaint at the time it was made.” (quoting Hebron v. Touhy, 18 F.3d 421, 422 (7th Cir. 1994)). As such, the Court finds that there was probable cause to believe that O‘Boyle had just committed a crime.

Before continuing its analysis, the Court must first note that a warrant was not required for Defendants to arrest O‘Boyle inside his home. As the Seventh Circuit has explained elsewhere:

To assume that the warrant requirement really goes to the matter of arrest rather than the matter of entry . . . is wrong. Because (i) there is no general requirement that arrests be made with a warrant, and (ii) an arrest within premises is no more threatening or humiliating than a street arrest, it should be apparent that . . . it is the otherwise unauthorized entry and not the arrest which gives rise to the warrant requirement.

Sheik-Abdi v. McClellan, 37 F.3d 1240, 1245 (7th Cir. 1994) (quoting W. LaFave, 2 SEARCH AND SEIZURE: A TREATISE ON THE FOURTH AMENDMENT § 6.1 at 584 (2d ed. 1987) (internal quotation marks omitted) and citing United States v. White, 660 F.2d 1178, 1183 (7th Cir. 1981)); Milbeck v. George, 171 F.4th 930, 936 (7th Cir. 2026) (“Physical entry of the home is the chief evil against which . . . the Fourth Amendment is directed,’ and ‘the warrant procedure minimizes the danger of needless intrusions of that sort.‘” (quoting Payton v. New York, 445 U.S. 573, 585–86 (1980) (internal brackets omitted))). That is all to say, “[o]nce an officer has lawfully entered the premises . . . the Constitution does not require that he obtain a warrant before affecting an otherwise lawful arrest within.” McClellan, 37 F.3d at 1245 (collecting authorities); see also White, 660 F.2d at 1183 (“In the instant case . . . a magistrate‘s determination that probable cause for an arrest warrant was lacking (should such a determination have been made) would not have prevented the ultimate intrusion. . . . It [therefore] serves no purpose to require an arrest warrant where the same intrusion would occur whether or not the magistrate issues the warrant.“); see also Poulson v. Commonwealth, 913 S.E.2d 527, 533 (Va. 2025) (collecting courts that have adopted this interpretation).

In this case, Defendants had a lawful basis for entry into O‘Boyle‘s residence. See infra Section 4.2. The Court acknowledges that unlike McCellan and the other cases that the McCellan court (and the Poulson court) collected, this justification does not rest on consent or exigent circumstances. However, that is only because this case involves an individual on extended supervision subject to diminished rights and a state law that enables officers to enter his residence under different parameters than those that apply to those not on extended supervision. See infra Section 4.2. As explained in more detail below, those parameters were met, making the Defendants’ entry lawful, and because there was probable cause (as discussed earlier in this Section), Defendants’ arrest of O‘Boyle was “otherwise lawful.” McClellan, 37 F.3d at 1245.

4.2 Unlawful Entry

“The Supreme Court has stated that ‘a fundamental purpose of the Fourth Amendment is to safeguard individuals from unreasonable government invasions of legitimate privacy interests.‘” Bentz v. City of Kendallville, 577 F.3d 776, 781 (7th Cir. 2009) (quoting United States v. Chadwick, 433 U.S. 1, 11 (1977), abrogated on other grounds by California v. Acevedo, 500 U.S. 565 (1991)). “Thus, to bring a Fourth Amendment action for an unlawful search (or entry), a plaintiff must have a legitimate expectation of privacy that society recognizes as reasonable.” Id. at 781–82 (citing California v. Ciraolo, 476 U.S. 207, 211 (1986) and United States v. Sandoval–Vasquez, 435 F.3d 739, 743 (7th Cir. 2006)). “Warrantless searches and seizures within a home are considered presumptively unreasonable and a violation of the Fourth Amendment.” United States v. Huddleston, 593 F.3d 596, 600 (7th Cir. 2010) (citing United States v. Bell, 500 F.3d 609, 612 (7th Cir. 2007)).

However, “criminal offenders on community supervision have significantly diminished expectations of privacy.” United States v. Caya, 956 F.3d 498, 500 (7th Cir. 2020). “More specifically, the privacy expectations of offenders on postimprisonment supervision are weak and substantially outweighed by the government‘s strong interest in preventing recidivism and safely reintegrating offenders into society.” Id. Thus, the Supreme Court has upheld “warrantless,” “no-suspicion search[es] of a parolee,” at least where there also existed a “release condition, regulation, or statute” authorizing such a search. Id. at 503 (citing Samson v. California, 547 U.S. 843 (2006)); Samson, 547 U.S. at 846 (addressing a search conducted on a public street under a state law authorizing parole and law-enforcement officers to search parolees “with or without a search warrant and with or without cause.” (internal citations omitted). Below, the Court will explain how this precedent applies to the facts and laws implicated here.

The Court finds that Defendants are entitled to summary judgment as to O‘Boyle‘s unlawful entry claim because it was constitutional for them to enter O‘Boyle‘s residence. An independent basis for granting Defendants summary judgment is that they are entitled to qualified immunity, in any event, because their entry was not in violation of a clearly established right. The Court will explain each of these bases in turn.

First, Defendants’ entry was constitutional because O‘Boyle was on extended supervision as a result of his felony conviction in his State Case at the time of their entry and because there exists a Wisconsin statute that authorizes Defendants to enter the residence of an extended supervisee as long as there exists reasonable suspicion of wrongdoing, and here, Defendants had not just reasonable suspicion, but probable cause. See infra Section 4.1. The applicable Wisconsin law here comes in the form of 2013 Wisconsin Act 79, see Caya, 956 F.3d 500, which provides that:

A person released under this section, his or her residence, and any property under his or her control may be searched by a law enforcement officer at any time during his or her period of supervision if the officer reasonably suspects that the person is committing, is about to commit, or has committed a crime or a violation of a condition of release to extended supervision.

WIS. STAT. § 302.113(7r).10 As the Caya court explained, Wisconsin‘s extended supervision program is effectively “parole by another name.” 956 F.3d at 503. Under the governing Supreme Court precedent established in Samson, 547 U.S. 843—which, as a reminder, allows for suspicionless searches in parolee cases—the Caya court upheld the constitutionality of Act 79 searches, which, as noted above, require at least reasonable suspicion for warrantless searches of an extended supervisee‘s residence. 956 F.3d at 503.

Since the standard for probable cause is greater than that of reasonable suspicion, United States v. Swift, 220 F.3d 502, 506 (7th Cir. 2000) (“Reasonable suspicion . . . is something less than probable cause and more than a hunch.” (citing United States v. Tipton, 3 F.3d 1119 (7th Cir. 1993))), this means that Defendants had more than enough justification to enter the O‘Boyle‘s residence. United States v. Chang, 999 F.3d 1059, 1063 (7th Cir. 2021) (noting that Act 79 “authorizes a law enforcement officer” who has reasonable suspicion to not only enter, but to conduct a search of the property of someone on extended supervision “without consent, a warrant, or probable cause“).

O‘Boyle correctly observes, ECF No. 89 at 3, that, as a general matter, “when the police . . . enter a home to arrest, if they have not obtained a warrant in advance, the entry and arrest are presumptively unlawful.”11 State. v. Ferguson, 767 N.W.2d 187 ¶ 17 (Wis. 2009) (citing Payton, 445 U.S. at 586; State v. Roberson, 717 N.W.3d 111 ¶ 31 n.12 (Wis. 2006); and State v. Hughes, 607 N.W.3d 621 (Wis. 2000)). However, his recitation of the law and analysis thereof is incomplete, as it does not analyze how this law applies to Wisconsin citizens on extended supervision. See ECF No. 87 at 20 (contending that Payton extends only to “law-abiding citizens” (citing Payton, 445 U.S. at 585)); id. at 21 (arguing that, per Caya and Act 79, Defendants did not need a warrant (or exigency) to arrest O‘Boyle). None of the cases O‘Boyle recites as requiring a warrant to enter the premises—including Ferguson—involve a parolee, an extended supervisee, or even a probationer, nor were any of them decided after the enactment of Act 79. See ECF No. 89 at 2–3. In fact, his selection of authorities, other than Ferguson, merely elaborate on what one must show to establish consent or exigent circumstances, giving the Court little more than a non-exhaustive list of exceptions to the warrant requirement. See, e.g., Schneckloth v. Bustamonte, 412 U.S. 218, 222 (1973) (discussing elements of consent); State v. Kiekhefer, 569 N.W.2d 316, 475 (Wis. Ct. App. 1997) (same) (citing Schneckloth, 412 U.S. at 222); Gautreaux v. State, 190 N.W.2d 542, 543 (Wis. 1971) (same) (internal citations omitted).

In failing to provide pertinent authority in support of his position that Defendants needed more than just reasonable suspicion to enter his residence at a time when he was on extended supervision, the Court considers his argument challenging the lawfulness of Defendants’ entry waived. Heather M. v. Berryhill, 384 F. Supp. 3d 928, 934–35 (N.D. Ill. 2019) (collecting cases); Norris v. Allstate Ins. Co., No. 3:22-CV-784 JD, 2023 WL 2571685, at *2 (N.D. Ind. Mar. 17, 2023) (“[E]ven pro se litigants are expected to file legal arguments with supporting authority because ‘[a] litigant who fails to press a point by supporting it with pertinent authority or by showing why it is sound despite a lack of supporting authority forfeits the point.‘” (quoting Mathis v. N.Y. Life Ins. Co., 133 F.3d 546, 548 (7th Cir. 1998))).

Second, O‘Boyle does not respond at all to Defendants’ argument that even if Defendants’ arrest of O‘Boyle was an unconstitutional arrest, qualified immunity applies. ECF No. 87 at 5–6, 9–11, 18–19, and 21; see generally ECF No. 89. This is fatal to his claim because “[o]nce a defendant raises a qualified-immunity defense, it becomes the plaintiff‘s burden to defeat it.” Strother v. Scott, 1:20-cv-00063-SEB-MJD, 2021 WL 4477873, at *3 (S.D. Ind. Sept. 30, 2021) (citing Rabin v. Flynn, 725 F.3d 628, 632 (7th Cir. 2013)). To defeat Defendants’ qualified immunity defense, O‘Boyle “needed to show—for each federal claim asserted—that (1) [Defendants] violated [his] constitutional right[]; and (2) the right was clearly established at the time of the challenged conduct.” Id. (citing Archer v. Chisholm, 870 F.3d 603, 613 (7th Cir. 2017)). As in Scott, “[t]he words ‘qualified immunity’ are absent from [O‘Boyle‘s] brief and the words ‘clearly established‘” are—even worse than in Scott (where this phrase was mentioned once in the plaintiffs’ brief)—never mentioned, not even once. Id.; see generally ECF No. 89. O‘Boyle has, therefore, waived any argument that Defendants are not entitled to qualified immunity in this case. Scott, 2021 WL 4477873, at *3 (citing Laborers Int‘l Union v. Caruso, 197 F.3d 1195, 1197 (7th Cir. 2003) and C & N Corp. v. Kane, 756 F.3d 1024, 1026 (7th Cir. 2014)); Thomas v. Carmichael, 164 F.4th 1058, 1068 (7th Cir. 2026) (Ripple, J., dissenting) (“In his response to the defendants’ motion for summary judgment, Mr. Thomas failed to respond to the defendants’ assertion that they were entitled to qualified immunity. Such an omission generally renders any opposition to qualified immunity waived or forfeited.“) (footnote omitted).

O‘Boyle‘s unlawful entry claim cannot survive for two independent reasons. First, Defendants needed only reasonable suspicion—and they had probable cause, see supra Section 4.1—because O‘Boyle was on extended supervision at the time of their entry and O‘Boyle provides no pertinent authority to challenge that Act 79, coupled with the Seventh Circuit‘s decision in Caya, justifies Defendants’ entry. Second, Defendants have argued that they are entitled to qualified immunity even if the Court finds an unlawful entry here because the circumstances did not amount to a clearly established right preventing entry, and O‘Boyle fails to address this argument.

4.3 Unlawful Arrest

“Officers violate the Fourth Amendment if they arrest an individual without probable cause.” Bartz v. Columbia County, No. 24-cv-671-jdp, 2026 WL 574621, at *2 (W.D. Wis. Mar. 2, 2026) (citing Gonzalez v. City of Elgin, 578 F.3d 526, 537 (7th Cir. 2009)). Because, as Defendants correctly note, probable cause is an absolute defense to an unlawful arrest claim. ECF No. 87 at 11 (citing Abbott, 705 F.3d at 713–14), and the Court has already found probable cause existed here, see supra Section 4.1, the Court finds that Defendants are entitled to summary judgment on the lawful arrest claim.

O‘Boyle appears to argue that Defendants needed more than just probable cause to arrest him. But he waived this argument because he again fails to provide pertinent authorities in support of his position. Berryhill, 384 F. Supp. 3d at 934–35 (collecting cases); Norris, 2023 WL 2571685, at *2 (citation omitted). In fact, one of the handful of authorities he selects opposes his position, that is, Wisconsin Statute § 968.07(1)(d). ECF No. 89 at 2. The plain language of that statute suggests that only probable cause is required to effectuate an arrest. WIS. STAT. § 968.07(1)(d) (noting that an officer can arrest if “[t]here are reasonable grounds to believe that [a] person is committing or has committed a crime.“). Strengthening the Court‘s interpretation is that the provisions in the surrounding statutory subdivisions allow for arrests if an officer has a warrant (or reason to believe that a warrant has been issued). WIS. STAT. § 968.07(a)–(c); Wittman v. Koenig, 831 F.3d 416, 422 (7th Cir. 2016) (“[S]tatutory language is interpreted in the context in which it is used; not in isolation but as part of a whole; in relation to the language of surrounding or closely-related statutes; and reasonably, to avoid absurd or unreasonable results.” (quoting State ex rel. Kalal v. Cir. Ct. for Dane Cnty., 681 N.W.2d 110 ¶ 46 (Wis. 2004))). Further supporting this interpretation is the Wisconsin Court of Appeals’ recent decision in State v. Benson, 934 N.W.2d 568 (Table), 2019 WL 3418481 (Wis. Ct. App. July 30, 2019). There, albeit in an unpublished decision, the Wisconsin Court of Appeals found that Wisconsin Statute § 968.07(d) does not require officers to obtain consent or possess exigent circumstances to perform a warrantless arrest in a defendant‘s home. Id. ¶ 34 (Wis. Ct. App. July 30, 2019) (noting that “[i]t is . . . of no import that police perhaps could have taken the time to secure a warrant: a warrant is not required to effectuate an arrest supported by

probable cause” (citing WIS. STAT. § 968.07(1)(d)); id. ¶ 34 n.9 (“[P]olice did not need consent to arrest [the defendant] because the arrest was supported by probable cause“).12

Meanwhile, the remaining authorities that O‘Boyle cites in support of his position are unavailing. ECF No. 89 at 2 (citing Jenkins v. Keating, 147 F.3d 577, 585 (7th Cir. 1998) and Payton, 445 U.S. at 585–90). Both cases, which supposedly establish that Defendants needed more than just probable cause, predate the enactment of Act 79 and do not engage the question of whether a warrantless arrest of a person on extended supervision, parole, probation is lawful. Jenkins, 147 F.3d 577 and Payton, 445 U.S. 573. In fact, in Jenkins, the Seventh Circuit determined that the defendant did not even arrest the plaintiff, indicating that the case contains no pertinent analysis. 147 F.3d at 583 (commenting only that the allegation was that defendant conducted an “unlawful arrest, that is, a seizure of her person without probable cause.“). The Court is not persuaded by these inapposite cases.

O‘Boyle‘s argument that Defendants unlawfully exercised “extra-jurisdictional arrest authority” fares no better. ECF No. 89 at 1 (citing WIS. STAT. § 175.40). The statute in contention provides that “[f]or any county having a population of 750,000 or more, if any law enforcement officer has territorial jurisdiction that is wholly or partially within that county and has authority to arrest a person within the officer‘s territorial jurisdiction, the officer may arrest that person anywhere in the county.” WIS. STAT. § 175.40(5)). The Court agrees with Defendants that this statute authorizes MPD to effectuate arrests anywhere within Milwaukee County, including at O‘Boyle‘s residence in Greenfield. ECF No. 87 at 17 (citing WIS. STAT. § 175.40(5)). To reach this conclusion, the Court takes judicial notice of the fact that Milwaukee County has more than 750,000 people.13 FED. R. EVID. 201(b); Helvey v. Acting Warden of FCI Greenville, No. 3:25-cv-00837-NJR, 2026 WL 555357, at *2 (S.D. Ill. Feb. 27, 2026) (“Examples of materials properly the subject of judicial notice include population data, geographic facts, weather records, and government records.” (citing 21B CHARLES ALAN WRIGHT & ARTHUR R. MILLER, FEDERAL PRACTICE & PROCEDURE § 5106.3 (2d ed.))); see, e.g., Skolnick v. Bd. of Comm‘rs of Cook Cnty., 435 F.2d 361, 363 (7th Cir. 1970) (taking judicial notice of the census data); Marshall v. Village of Dwight, 22-cv-01228-JES-JEH, 2023 WL 2316178, at *3 (C.D. Ill. Mar. 1, 2023) (same); Buchanan-Moore v. City of Milwaukee, 576 F. Supp. 2d 944, 954 (E.D. Wis. 2008) (same).

O‘Boyle‘s arguments as to why the statute does not apply here are unpersuasive. O‘Boyle first argues that the plain language of Wisconsin Statute § 175.40(5) requires that MPD arrest individuals only “in public,” but the statute does not say that, and the Court declines to read in such a limitation. Cf. Keith v. Sullivan, 956 F.3d 1478, 1482 (E.D. Wis. 1997) (“The respondents’ analysis of Wisconsin‘s civil commitment statute is flawed in that it assumes that the statute‘s requirement that the ‘sexually violent’ prisoner be within 90 days of release is also a requirement that the commitment be based solely on the conviction for which the prisoner is incarcerated. A plain-reading of the statute, however, reveals no such requirement.“); Johnson v. Larson-Smith, 13–cv–309–wmc, 2015 WL 3755965, at *5 (W.D. Wis. June 16, 2015) (declining to require prisoner to plead in detail every grievance before he can be said to have exhausted remedies, in part, because the “Wisconsin Administrative Code contains no such requirement” (citing Strong v. David, 297 F.3d 646, 649 (7th Cir. 2002))).14

His remaining arguments fare no better, as they are predicated on 1) what MPD officers would need to show if they made an arrest outside their jurisdiction (such as in a case of hot pursuit) and 2) the implied notion that the City of Greenfield is not part of Milwaukee County. ECF No. 89 at 1 (internal citations omitted). However, the Court will take judicial notice of the fact that City of Greenfield is part of Milwaukee County15 and will dispense with his remaining arguments. FED. R. EVID. 201(b); Helvey, 2026 WL 555357, at *2 (citation omitted).

Because there was probable cause in this case, see supra Section 4.1, and because O‘Boyle wholly fails to provide pertinent legal authority that more than probable cause was legally necessary for MPD to arrest him in his residence on November 24, 2022, the Court will grant summary judgment to Defendants on O‘Boyle‘s unlawful arrest claim. As an independent basis for this holding, the Court will grant summary judgment to Defendants on the unlawful arrest claim because O‘Boyle fails to address Defendants’ invocation of qualified immunity in any way. See supra Section 4.2.

4.4 False Imprisonment under Fourth Amendment

“False arrest and false imprisonment overlap; the former is a species of the latter.” Wallace v. Kato, 549 U.S. 384, 388 (2007) (speaking in the context of § 1983 claims like this one). “Every confinement of the person is an imprisonment, whether it be in a common prison or in a private house, or in the stocks, or even by forcibly detaining one in the public streets; and when a man is lawfully in a house, it is imprisonment to prevent him from leaving the room in which he is.” Id. at 388–89 (citations omitted). As such, “a plaintiff may establish . . . a § 1983 claim . . . [for] false imprisonment . . . where his freedom of movement was limited or restrained in some way without probable cause.” Bentz, 577 F.3d at 780 (citing Bielanski v. County of Kane, 550 F.3d 632, 637 (7th Cir. 2008)) (additional citation omitted).

The Court will grant summary judgment to Defendants as to O‘Boyle‘s federal false imprisonment claim. ECF No. 81 at 3 n.5 (noting that O‘Boyle has a false imprisonment claim that he believes sounds in both federal and state law). Because Defendants had probable cause to arrest O‘Boyle, see supra Section 4.1, and because probable cause is an absolute defense to false imprisonment—Abbott, 705 F.3d at 713–714 (citation omitted)—the Court will grant summary judgment to Defendants on this claim.

As an independent basis for this holding, the Court will grant summary judgment to Defendants as to O‘Boyle‘s Fourth Amendment false imprisonment claim because O‘Boyle fails to address Defendants’ invocation of qualified immunity in any way. See supra Section 4.2.

4.5 Excessive Force

“An officer‘s use of force is unreasonable from a constitutional point of view if, judging from the totality of circumstances at the time of the arrest, the officer used greater force than was reasonably necessary to make the arrest.” Green v. Chvala, 567 F. App‘x 458, 461 (7th Cir. 2014) (quoting Gonzalez, 578 F.3d at 539. “Significant force may not be used on nonresisting or passively resisting suspects.” Id. (citing Abbott, 705 F.3d at 732).

The Court will grant summary judgment to Defendants as to O‘Boyle‘s excessive force claim. In the parties’ joint statement of undisputed facts, O‘Boyle agreed that he “does not allege any injury arising from the manner in which he was secured; he claims only that warrantless seizure within his home was objectively unreasonable (i.e.[,] excessive) under the circumstances.” ECF No. 81 at 8. In other words, O‘Boyle‘s excessive force claim depends on Defendants’ November 24, 2022 entry and arrest being unlawful—to the extent he even seeks to pursue the claim at all. See generally ECF No. 89 at 5 (not discussing excessive force once). Therefore, because the Court has found that Defendants’ entry and arrest of O‘Boyle were lawful, see supra Sections 4.2 and 4.3, his excessive force claim must also fail.

Further, O‘Boyle fails to state a claim for excessive force. Townsel v. Jamerson, 240 F. Supp. 3d 894, 904 (N.D. Ill. 2017) (noting that the Supreme Court and the Seventh Circuit have “held that ‘there cannot be excessive force without some force‘” (quoting McNair v. Coffey, 279 F.3d 463, 467 (7th Cir. 2002) and citing Chriswell v. Village of Oak Lawn, No. 11 C 00547, 2013 WL 5903417, at *9 (N.D. Ill. Nov. 4, 2013), aff‘d sub nom. by Chriswell v. O‘Brien, 570 F. App‘x 617 (7th Cir. 2014) and Mannix v. Humer, No. 10 C 5063, 2011 WL 116888, at *3 (N.D. Ill. Jan. 11, 2011))). The Court will accordingly grant summary judgment to Defendants on O‘Boyle‘s excessive force claim.

4.6 Unlawful Post-Seizure Detention/Arrest

The Fourth Amendment protects individuals against “unreasonable . . . seizures.” U.S. CONST. AMEND. IV. “A person has been seized within the meaning of the Fourth Amendment only if, in view of all the circumstances surrounding the incident, a reasonable person would have believed that he was not free to leave.” Isreal v. Chovance, No. 24-CV-18-JPS, 2024 WL 385912, at *3 (E.D. Wis. Feb. 1, 2024) (quoting California v. Hodari D., 499 U.S. 621, 628–29 (1991) (internal brackets and quotation marks omitted)). “The Fourth Amendment prohibits government officials from detaining a person in the absence of probable cause.” Manuel v. City of Joliet, 580 U.S. 357, 367 (2017) (citation omitted).

The Court will grant summary judgment to Defendants on O‘Boyle‘s post-seizure detention/arrest claim. Although the parties do not agree on the timeline that forms the basis of this claim, Defendants are entitled to summary judgment under either proposed timeline.

Defendants seem to suggest that any potential liability would be limited to the time between 2:15 to 3:07 a.m., which was the timeframe during which Defendants escorted O‘Boyle to the police station, because at 3:07 a.m. DOC “issued a ‘hold’ to detain O‘Boyle . . . based on new criminal activity and violating the terms of supervision.” ECF No. 87 at 3 (citing ECF No. 85-12); ECF No. 87 at 24 (arguing that “the Department [of Corrections] exercised independent authority in ordering him held which constitutes an intervening, superseding event that terminates these defendant-officers’ liability for Plaintiff‘s continuing detention“). O‘Boyle argues his detention both before and after 3:07 a.m. was unlawful. See ECF No. 89 at 5 (“Defendants’ . . . assertion that [O‘Boyle] has been held pursuant to DOC authority since 3:07 am on November 24, 2022, and that even if his initial arrest and detention were unlawful, these Defendants are only personally liable for his confinement between 2:15 and 3:07 am, is simply untrue . . . .“).

On the one hand, to the extent the relevant period is 2:15 a.m. to 3:07 a.m. (the time transporting O‘Boyle to the police station), this detention is “part and parcel to [his] arrest,” Mutter v. Sanders, 611 F. Supp. 2d 837, 843 (C.D. Ill. 2009) (citing Kato, 549 U.S. at 390), and the Court has already found his arrest to be lawful. See supra Section 4.3. Therefore, O‘Boyle cannot advance an unlawful detention claim within this timeline. Van Dyke v. Cook Cnty. Sheriff‘s Off., No. 21-CV-01448, 2022 WL 4483835, at *9 (N.D. Ill. Sept. 27, 2022) (“Plaintiff fails to allege a plausible Fourth Amendment false arrest claim . . . . And because she cannot allege a false arrest claim, her claim for unlawful detention . . . based on that arrest also fails.“); Olzinski v. Maciona, 714 F. Supp. 401, 408 (E.D. Wis. 1989) (“[T]he existence of sufficient cause for arrest precludes any section 1983 claim for unlawful arrest and detention.” (citing Mark v. Furay, 769 F.2d 1266, 1268–69 (7th Cir. 1985))).

Because Defendants are entitled to qualified immunity as to the unlawful arrest, see supra Section 4.3, they are also, by this same logic, entitled to qualified immunity as to the unlawful detention. Robinson v. Gerritson, 210 F.2d 1004, 1013 (N.D. Ill. 2002) (“Robinson‘s unconstitutional detention claim still fails. And that is so for precisely the same reason that was fatal to her unlawful arrest claim: that a reasonable officer could have concluded, even if mistakenly, that there was probable cause to arrest her.“); Hill v. City of Harvey, 732 F. Supp. 3d 862, 876 (N.D. Ill. 2024) (“[Q]ualified immunity protects officers who have a reasonable, albeit mistaken belief that probable cause existed” to arrest a person) (citing Abbott, 705 F.3d at 715 and citing Hunter v. Bryant, 502 U.S. 224, 227 (1991))).

And, to the extent that O‘Boyle challenges the restraint on his liberty after he arrived the police station at 3:07 a.m., that argument falls flat because he fails to meaningfully engage with Defendants’ argument that he was then in DOC custody—owing to his status as an extended supervisee under investigation under Wisconsin Statute § 302.113(8m)(a)—rather than MPD custody. ECF No. 87 at 3, 24–25; c.f. Swanigan v. Trotter, 645 F. Supp. 2d 656, 677 (N.D. Ill. 2009) (“An arresting officer is not responsible for the plaintiff‘s detention once he turns the plaintiff over to jailers at the police station.” (citing Tibbs v. City of Chicago, 469 F.3d 661, 665 (7th Cir. 2006))). Defendants are, therefore, entitled to summary judgment on O‘Boyle‘s unlawful post-seizure detention/arrest claim.

4.7 Failure to Intervene under Federal Law

To succeed on his failure to intervene claim, O‘Boyle “must demonstrate that . . . Defendants (1) knew that a constitutional violation was committed; and (2) had a realistic opportunity to prevent it.” Gill v. City of Milwaukee, 850 F.3d 335, 342 (7th Cir. 2017) (citing Yang v. Hardin, 37 F.3d 282, 285 (7th Cir. 1994)). As explained infra Sections 4.1–4.6, there were no “underlying constitutional violation[s],” committed against O‘Boyle here, leaving his federal failure to intervene claim with “no legs to stand on.” Higgins v. Jeffreys, No. 3:23 C 50038, 2026 WL 1266186, at *14 (N.D. Ill. May 8, 2026) (citing Harper v. Albert, 400 F.3d 1052, 1064 (7th Cir. 2005)). As such, the Court must grant summary judgment to Defendants as to O‘Boyle‘s federal failure to intervene claim.

4.8 State Law Claims

O‘Boyle also alleges false imprisonment and failure to intervene claims under state law. ECF No. 81 at 3 n.5 (noting that O‘Boyle alleges a false imprisonment claim not just under federal law, but state law as well); see Herbst v. Wuennenberg, 266 N.W.2d 391, 394–95 (Wis. 1978) (discussing tort of false imprisonment under state law); WIS. STAT. § 175.44(4) (duty to intervene statute in cases of excessive force).16 Because the Court has ruled in favor of Defendants on all of O‘Boyle‘s federal law claims, it declines to exercise jurisdiction over the remaining state law claims. 28 U.S.C. § 1367(c)(3). See also Pyles v. Daily, No. 19-cv-1067-JPG, 2023 WL 3978513, at *7 (S.D. Ill. June 13, 2023) (citing Braun v. Village of Palatine, 56 F.4th 542, 545 (7th Cir. 2022), reh‘g denied, No. 20-3227, 2023 WL 2188741 (7th Cir. Feb. 23, 2023) (affirming relinquishing jurisdiction over remaining state law claims after finding that officer had probable cause to arrest plaintiff on a § 1983 claim).

5. CONCLUSION

For the forgoing reasons, the Court concludes that none of O‘Boyle‘s federal law claims withstand summary judgment. The Court will, therefore, grant summary judgment as to the federal law claims, which will be dismissed with prejudice. The Court will decline to exercise supplemental jurisdiction over O‘Boyle‘s remaining state law claims, which will be dismissed without prejudice. With all claims having been addressed, the case will be dismissed.

Accordingly,

IT IS ORDERED that Defendants Mark Sheremeta, Ana Romero-Perez, Kristopher Maduscha, Nash Dathe, Nathan Locicero, and Shawn Humitz‘s motion for summary judgment, ECF No. 80, be and the same is hereby GRANTED in part, to the extent it concerns Plaintiff Ryan O‘Boyle‘s federal law claims;

IT IS FURTHER ORDERED that Plaintiff Ryan O‘Boyle‘s federal law claims be and the same are hereby DISMISSED with prejudice;

IT IS FURTHER ORDERED that, pursuant to 28 U.S.C. § 1367(c), the Court declines to exercise supplemental jurisdiction over Plaintiff Ryan O‘Boyle‘s state law claims, which be and the same are hereby DISMISSED without prejudice;

IT IS FURTHER ORDERED that Plaintiff Ryan O‘Boyle‘s motion for summary judgment, ECF No. 89, be and the same is hereby DENIED; and

IT IS FURTHER ORDERED that this action be and the same is hereby DISMISSED.

The Clerk of Court is directed to enter judgment accordingly.

Dated at Milwaukee, Wisconsin, this 31st day of August, 2026.

BY THE COURT:

J. P. Stadtmueller

U.S. District Judge

This Order and the judgment to follow are final. A dissatisfied party may appeal this Court‘s decision to the Court of Appeals for the Seventh Circuit by filing in this Court a notice of appeal within thirty (30) days of the entry of judgment. See FED. R. APP. P. 3, 4. This Court may extend this deadline if a party timely requests an extension and shows good cause or excusable neglect for not being able to meet the thirty-day deadline. See FED. R. APP. P. 4(a)(5)(A). Moreover, under certain circumstances, a party may ask this Court to alter or amend its judgment under Federal Rule of Civil Procedure 59(e) or ask for relief from judgment under Federal Rule of Civil Procedure 60(b). Any motion under Federal Rule of Civil Procedure 59(e) must be filed within twenty-eight (28) days of the entry of judgment. The Court cannot extend this deadline. See FED. R. CIV. P. 6(b)(2). Any motion under Federal Rule of Civil Procedure 60(b) must be filed within a reasonable time, generally no more than one year after the entry of the judgment. The Court cannot extend this deadline. See id. A party is expected to closely review all applicable rules and determine what, if any, further action is appropriate in a case.

Notes

1
Although the Court has construed O‘Boyle‘s filing as an opposition brief, the submission was docketed as a motion for summary judgment based on the manner in which O‘Boyle entitled it. Given the disposition of O‘Boyle‘s claims as described, the Court will deny O‘Boyle‘s filing at ECF No. 89 to dispose of the “motion.”
2
The facts in this section are drawn largely from the parties’ joint statements of undisputed facts. ECF No. 81. Some facts from the joint statement are omitted as immaterial. Internal citations from the joint statement of facts are omitted in this section, except where helpful to provide additional context. The Court also cites to facts from other portions of the record as necessary, including body camera footage provided to the Court by Defendants, and notes any disputes as relevant.
3
According to O‘Boyle, the Complaining Witness allegedly provided these details within 36 seconds of Sheremeta and Romero-Perez‘s arrival, and the details sounded well-rehearsed. ECF No. 81 at 4 n.7.
4
O‘Boyle claims the recording reveals that at that time the Complaining Witness also reported she “had never seen and could not describe the guns.” Id. at 5. Defendants say that the video speaks for itself. Id. Based on the Court‘s review, it is true that the Complaining Witness reported that she had never seen the guns personally. ECF No. 85-15 at 30:55 to 31:30. It is also true, however, that during that same conversation, she reported that O‘Boyle had told her that he has two guns in the basement, including a .44, though she could not say what that terminology “means” in terms of whether a .44 referred to a rifle, pistol, or whatever the case may be. Id.
5
O‘Boyle claims that Sheremeta did not use the word “please” here, ECF No. 81 at 7, but review of the footage reveals that he did. ECF No. 85-17 at 13:10 to 13:15. In any event, this fact is immaterial because no consent was required. See infra Sections 4.2 and 4.3.
6
While the parties seem to use the terms “probation” and “parole” interchangeably, the Court will use the correct term of “supervised release” where appropriate in this Order. “Formally and practically, Wisconsin‘s extended-supervision system,” which the parties agree O‘Boyle was on at the time of the arrest, “is parole by another name.” United States v. Caya, 956 F.3d 500, 503 (7th Cir. 2020).
7
O‘Boyle challenges whether Defendants engaged in good-faith discovery to undermine the evidence Defendants attached on summary judgment. ECF No. 89 at 1. However, at this point, since the Court already analyzed these arguments in a prior order denying default judgment and determined they have no merit, ECF No. 67, the Court has no occasion to address the matter again and will not do so here.
8
The Court notes that the standard used in the context of Act 79, namely, reasonable suspicion, “is the same [as] in federal court.” United States v. Slater, No. 21-CR-106-PP-SCD, 2021 WL 7500271, at *8 (E.D. Wis. Oct. 21, 2021), report and recommendation adopted by 2022 WL 558097 (E.D. Wis. Feb. 24, 2022) (citing Navarette v. California, 572 U.S. 393, 396–97 (2014) and United States v. Chang, 999 F.3d 1059, 1065–67 (7th Cir. 2021)); id. (reciting the reasonable suspicion standard used in Act 79 cases (quoting State v. Anderson, 935 N.W.2d 285, ¶ 33 (Wis. 2019)); see id. (finding that “totality of the circumstances here demonstrate that the police had reasonable suspicion to believe that Slater had committed, was committing, or was about to commit a crime“). By extension, therefore, the Court sees no reason that the Court could not also borrow the probable cause analysis used in other Fourth Amendment cases, and will accordingly do so here.

O‘Boyle makes the far-fetched allegation that the DOC operated as “stalking horse” by requesting a probation hold and using a “CR-215 form” to “induce a Judge to find probable cause to cover up their illegal acts.” ECF No. 89 at 4–5. This is an unsubstantiated assertion, as O‘Boyle provides no evidence to suggest any such intent from the MPD or even the existence of the “CR-215 form” to which he refers. Therefore, the Court considers this argument waived. Lee v. Chi. Youth Ctrs., 69 F. Supp. 3d 885, 888 (N.D. Ill. 2014) (“An argument is waived by failure to properly support and develop in the brief the factual basis essential to its disposition.” (citing Morgan v. S. Bend Cmty. Sch. Corp., 797 F.2d 471, 480 (7th Cir. 1986))). And even if O‘Boyle had properly developed and substantiated this claim, the “stalking horse theory has no application” in a case like this where Defendants rely on “ordinary Fourth Amendment analysis that considers all the circumstances” of the alleged Fourth Amendment intrusion. United States v. Price, 28 F.4th 739, 751–52 (7th Cir. 2022) (citing United States v. Knights, 534 U.S. 112, 122 (2001) and United States v. Sweeney, 891 F.3d 232, 236 (6th Cir. 2018)).

This Court rejects O‘Boyle‘s argument (which appeared in a letter to the Court well past the summary judgment briefing deadline) that “Defendants never mentioned Act 79 on November 24, 2022,” the date of the incident, and, therefore, cannot utilize it now, ECF No. 95 at 1. Nothing in the statute‘s plain language requires “officers to refer to the search as an ‘Act 79 search’ either prior to its execution or in subsequent communications.” United States v. Wicks, No. 20-CR-143-JPS, 2021 WL 4786307, at *2 (E.D. Wis. Oct. 13, 2021) (citing United States v. Berkos, 543 F.3d 392, 398 (7th Cir. 2008)); Slater, 2022 WL 558097, at *22 (citing Wicks, 2021 WL 4786307, at *2) (rejecting the same argument). To the extent that O‘Boyle separately challenges whether Defendants timely raised the Act 79 as a defense in this litigation, ECF No. 95 at 1, the Court will also dispense with that argument because, as Defendants point out, they included it as one of their affirmative defenses. ECF No. 96 at 2 (citing ECF No. 49 at 21).

Because the whole quote also speaks to O‘Boyle‘s argument on his unlawful arrest claim, discussed later this in this section, the Court includes it here.

12In Benson, the state court never suggests that Benson was on extended supervision or probation at the time of the warrantless arrest in his house, a reality that the Court believes would have lowered the standard from requiring probable cause to merely having a reasonable suspicion that the defendant had committed a crime. See generally State v. Benson, 934 N.W.2d 568 (Table), 2019 WL 3418481 (Wis. Ct. App. July 30, 2019); see supra Section 4.2.

14O‘Boyle also argues that Defendants needed to obtain “additional arrest authority,” ECF No. 89 at 2, but the Court sees no authority or reason to suggest this is true, and O‘Boyle has provided none.
