A confidential informant told the St. Clair County Sheriffs Drug Tactical Unit (“DTU”) that she could purchase crack cocaine from defendant-appellant Tavon A. Upton at his home in Cahokia, Illinois. On July 9 and July 15, 2003, under police supervision, she did just that. Using the evidence from these controlled buys, Investigator Timothy Bedard applied for a warrant to search Upton’s home and, on July 16, 2003, Bedard and members of the DTU executed the warrant. When he saw the DTU approaching, Upton bolted, discarding two baggies containing cocaine base and cocaine as he ran. The police soon caught up, arrested him, and drove him — literally kicking and screaming — to *396 the police station, where he confessed to selling drugs out of his house. The search of Upton’s home — producing an assortment of drug paraphernalia, digital scales, two knives, and a .380 caliber handgun— confirmed his confession.
An indictment followed and, on April 26, 2006, convictions for one count of being a felon in possession of a firearm in violation of 18 U.S.C. § 922(g)(1) and one count each for possessing with intent to distribute cocaine base and cocaine in violation of 21 U.S.C. § 841(a)(1). The district court then sentenced Upton to 288 months’ imprisonment, a 5-year term of supervised release, a special assessment, and a fíne. Upton now appeals, challenging the admissibility of his confession, an officer’s expert testimony given at trial, the jury instructions, and his enhanced sentence for being a career criminal. Finding no error, we affirm both his convictions and his sentence.
I. Background
A. Factual History
In July 2003, a confidential informant learned that Upton had been selling crack cocaine out of his home in Cahokia — a city in southwest Illinois on the border with Missouri' — and contacted Officer Timothy Bedard. Officer Bedard was an officer in the Cahokia Police Department and the St. Clair County Sheriffs Drug Tactical Unit (“DTU”). On July 9 and again on July 15, 2003, under Bedard’s supervision, the confidential informant engaged in two controlled buys of crack cocaine out of Upton’s home. Using the information from these buys, Bedard obtained a search warrant for Upton’s address and, the next day, Bedard and several other members of the DTU executed the warrant. When the DTU pulled up to his home, Upton was standing in his driveway. Rightly guessing that the approaching battalion of police in riot gear was not a good sign, he took off running. The police caught him and recovered two plastic bags, containing what the police later determined to be 4.4 grams of cocaine and 4.8 grams of cocaine base.
For his part, Upton was not the model arrestee. While Bedard was initially reading him his Miranda rights, Upton began yelling that he was not going to return to prison. During the ensuing frisk, he became more aggressive, refusing to cooperate with the police and pulling away from and even kicking at the officers. And when the officers tried to put him in the squad car, he resisted their efforts— though they eventually succeeded.
Another Cahokia police officer, Phillip Taylor, and his partner then drove Upton to the police station. On the way, Upton’s antics only worsened. After only a few blocks, he began kicking the squad car’s side window and door with both feet, eventually causing the door and window to bow out. Taylor stopped the car, opened the door, and attempted to pacify Upton, but to no avail. Seemingly at a dead end, Taylor delivered what’s called a “palm strike” in an effort to get Upton back in the car. 1 He was not aiming for Upton’s nose — he testified that he was trying to hit Upton’s torso. But when Upton lowered his head mid-strike, that’s where his palm landed. Though errant, the move was successful. Upton abandoned his efforts to leave the car, and Taylor was able to close the door and continue on. After his booking, Taylor then tended to a cut on Upton’s nose (the “palm strike” had produced a *397 small laceration), which stanched the bleeding.
A few minutes later, another Cahokia police officer, Deputy Bill Kenny, transported Upton to the St. Clair County Jail. On the way, Upton told Deputy Kenny that he wanted to work as an informant for another Cahokia police officer whom Upton knew, Detective Kurt Evers-man. The conversation did not go much further, and Kenny delivered Upton to the county jail.
While all this was going on, Bedard and the DTU had been searching Upton’s residence. The fruits of the search confirmed suspicions that Upton had been dealing drugs: marijuana recovered from the kitchen and Upton’s truck; cocaine from a kitchen cabinet; a digital scale with residue on it; boxes of plastic bags; bottles of prescription drugs not prescribed to Upton; a. 380 caliber Tanfoglio firearm and ammunition; a police radio scanner; a large knuckle-knife with a steel-spiked handguard; and a switchblade. Bedard inventoried what the DTU had found and went to the county jail to question Upton.
Bedard, Detective Eversman, and another officer conducted the interview. Be-dard first read Upton his Miranda rights a second time, but Upton refused to sign an acknowledgment form. Still, Upton answered the officers’ questions, repeating his earlier offer to cooperate with the police in exchange for a lowered sentence. Upton then proceeded to make several incriminating statements. He confessed to selling drugs out of his home in order to support his child. And he also explained that he was a user; in fact, he had smoked crack just before his arrest, perhaps explaining his outburst in the squad car. When confronted with the fact that the police had removed a .380 caliber gun from his home, Upton admitted that he had handled it, but said that it belonged to a friend. At trial, the officers would testify that Upton was composed throughout the interview, and he did not give any outward indication that he was still in pain from his cut nose. Despite his apparent cooperation, at the end of the interview Upton refused to sign a written statement memorializing his confession.
Upton never did end up identifying other drug dealers, and on April 5, 2006, a grand jury returned a five-count indictment against Upton charging (i) possession of a firearm by a felon in violation of 18 U.S.C. § 922(g)(1); (ii) possession of cocaine base with intent to distribute in violation of 21 U.S.C. § 841(a)(1); (iii) possession of cocaine with intent to distribute in violation of 21 U.S.C. § 841(a)(1); (iv) possession of a firearm in relation to a drug-trafficking offense in violation of 18 U.S.C. § 924(c)(1); and (v) forfeiture of the firearm involved in a drug-trafficking offense pursuant to 18 U.S.C. § 924(d).
B. Procedural History
Prior to his trial, Upton sought to suppress his post-arrest statements, claiming that his Miranda waiver had not been voluntary. To shore up his claim, Upton pointed to his injured nose and his refusal to sign a Miranda waiver. After briefing and a hearing, the district court denied Upton’s motion. The court found that Upton had been “combative and uncooperative” and that he had received his bloodied nose “as a result of his behavior during his arrest and transportation to the Cahokia Police Department,” not due to police overreaching. Further, Upton’s efforts “to help himself by cooperating, essentially to stay out of jail” overshadowed any inference of police overreaching that could be drawn from a refusal to sign the Miranda waiver.
At trial, the government would prove its case against Upton through the testimony of the various officers involved in Upton’s *398 arrest, Upton’s confession, and the physical evidence seized from his home. Upton objected to the fact that Officer Eversman would testify as both an expert and a lay witness. Eversman had expertise on the drug trade, such as the use of firearms in drug trafficking, the tools of the trade, and why the amount of drugs seized from Upton’s home indicated an intent to distribute. But he would also testify as a lay witness regarding Upton’s confession, the controlled buys, the execution of the search warrant, and the particulars of Upton’s arrest. Upton was concerned that the jury would not be able to separate the two kinds of testimony and noted this potential prejudice to the court. To obviate any prejudice, the government agreed to clearly separate Everman’s expert and lay testimony. In addition, prior to his testimony, the court instructed the jury that “Lieutenant Eversman will testify as both a fact witness and an expert witness,” to put them on guard. Finally, as promised by the government, the court took a twenty minute recess between Eversman’s lay testimony and his expert testimony.
During Eversman’s expert testimony, Upton objected to several questions posed by the government, claiming that they blurred the distinction between lay and expert testimony or were not helpful to the jury. The court sustained several objections, concluding that they were not helpful to the jury or that the government had asked a question going to fact testimony during Eversman’s expert testimony. For example, the court sustained an objection to a question asking Eversman about the contents of Upton’s confession during the expert portion of his testimony. The court also overruled objections to questions asking Eversman to comment on particular pieces of evidence. Thus, the government could not ask whether the location of the gun seized in the search of Upton’s home was consistent with the location of firearms in other drug-related premises. And, in a sidebar, the court limited Evers-man’s expert testimony regarding the use of knives by drug dealers, permitting the testimony in general terms but not allowing the particular knives to appear during the testimony.
As trial finished up, the parties moved to instructing the jury. Upton proposed two lesser-ineluded-offense instructions of simple possession for both distribution counts. The district court denied Upton’s request, stating that the evidence did not support simple possession. On April 26, 2006, the jury returned its verdict, convicting Upton of being a felon in possession of a firearm and both distribution counts, but acquitting him of possessing the firearm in relation to drug trafficking.
On February 21, 2007, the district court sentenced Upton to 288 months’ imprisonment and five years’ supervised release. The district court determined that Upton qualified as an Armed Career Criminal under 18 U.S.C. § 924(e). In so doing, the court was satisfied that .Upton’s prior convictions for aggravated battery, possession of a sawed-off shotgun, and three instances of domestic battery qualified as predicate offenses, and applied the enhancement. This appeal followed.
II. Discussion
Upton’s appeal focuses on the district court’s pre-trial and trial rulings as well as the ultimate sentence imposed. Specifically, Upton challenges the voluntariness of his Miranda waiver, the admission of Ev-ersman’s expert and lay testimony, the district court’s denial of the lesser-included-offense instructions, and his status as an Armed Career Criminal. The following sections discuss each in turn.
*399 A. Voluntariness of Miranda Waiver
On appeal, Upton reiterates his claim that his Miranda waiver had not been knowing and voluntary and that his subsequent confession was thus inadmissible. Upton argues that the series of events surrounding his nose injury rendered his Miranda waiver involuntary. He points to the fact that he was cantankerous immediately after his arrest, but then became docile after the poorly landed “palm strike” injured his nose. Although Officer Taylor treated the cut on his nose, Upton did not receive any additional medical attention. Nor did a significant period of time pass between the injury and the interview in which he confessed. Finally, he points to his refusal to sign either an acknowledgment of his rights or a written statement during the interview.
When viewed in context, there is no indication that any of this affected Upton’s
Miranda
waiver. This Court reviews de novo whether a
Miranda
waiver was voluntary and reviews the district court’s findings of historical facts for clear error.
United States v. Smith,
Upton impliedly waived his
Miranda
rights before he confessed. Granted he did not sign an acknowledgment form after Bedard read him his rights a second time. But he told the officers that he understood his rights, even requesting an attorney after he had confessed. And he did freely talk about the allegations against him, admitting they were true but attempting to strike a deal.
United States v. Smith,
In addition, the circumstances surrounding his arrest and confession satisfy us that, despite the “palm strike,” Upton’s waiver was voluntary. Although physical force is certainly a defining circumstance — and possibly a dispositive one,
see Miller v. Fenton,
Upton’s injury resulted in large measure from his own misconduct, not police efforts to coerce him into waiving his rights.
See Colorado v. Connelly,
In addition, there was a clear break in the chain of events between the injury and the interview.
Holland,
Finally, Upton’s efforts to secure a better deal for himself show that he had a calculating and not a cowed mind at the time of his confession. When traveling with Officer Kenny to the county jail, Upton first raised the prospect of cooperating to lessen his criminal exposure. Again during the interview, Upton raised the possibility of cooperating with Bedard and Eversman. As the district court found, his efforts to secure a deal coupled with his refusals to sign a written confession or an acknowledgment of his rights are telling.
See Smith,
B. Officer Eversman’s Testimony
Upton also argues that several questions posed to Officer Eversman failed to properly distinguish between his roles as an expert and lay witness. Upton concedes that the district court offered a cautionary instruction prior to Eversman’s testimony and that his attorney probed the distinction between lay and expert testimony in cross-examination. But Upton argues that several government questions failed to highlight the exact capacity in which Eversman was testifying. For example, he points to questions posed to *401 Eversman-the-expert concerning what Upton said after his arrest, a factual issue. The district court also restricted questions regarding whether the location of the gun in Upton’s home was consistent with what Eversman had seen in other drug premises. Several other questions simply went beyond Eversman’s capacity as an expert. Although the court sustained several of his objections, Upton claims these questions polluted the trial and require reversal.
Whatever potential prejudice may arise from dual expert and fact testimony, none occurred here. This Court reviews a district court’s decision to admit expert testimony for an abuse of discretion.
United States v. de Soto,
But it is precisely because an expert provides much of the structure for the jury’s understanding of the drug trade that courts must be mindful when the same witness provides both lay and expert testimony. The jury may unduly credit the witness’s fact testimony given his status as an expert.
Brown,
But none of these forms of possible prejudice arose in Upton’s case. Before Ev-ersman’s testimony, the district court gave a cautionary instruction explaining that Eversman would be serving both functions as a witness,
de Soto,
C. Denied Lesser-Included-Offense Instructions
Upton also argues on appeal that the district court erred in denying his request for lesser-included-offense instructions of simple possession. The amount of drugs actually seized following his arrest— 4.4 grams of cocaine and 4.8 grams of crack — were not so large as to compel a finding of intent to distribute. The two sales to the confidential informant also involved only a small amount of crack. And Upton was a user, or so he admitted to the police following his arrest. This evidence, he argues, is consistent with a finding that he was a simple drug user who had no intention to distribute, justifying a simple possession instruction. We disagree.
This Court’s review of a district court’s denial of a lesser-included-offense instruction has both a legal and a factual component. The defendant must first establish that the requested instruction is for an offense necessarily included in the one charged.
United States v. McCullough,
The district court properly denied both of Upton’s requests for simple possession instructions. In the first place, simple possession of cocaine base is not a lesser-included offense for possessing a controlled substance with an intent to distribute.
United States v. Steward,
*403
Nor was Upton entitled to a simple possession instruction for the cocaine count, albeit for a different reason. Unlike cocaine base, the simple possession of cocaine is a lesser-included offense to the possession of cocaine with intent to distribute.
See United States v. Puckett,
Further, the items seized from his home indicate Upton had set up a drug retail operation: marijuana, blue pills hidden in a cigarette box, another baggy of cocaine next to a digital scale for weighing out small drug quantities, white residue on the digital scale, small baggies used for distributing product to customers, a police scanner to guard against approaching law enforcement, weapons for self-help, prescription drugs that were not prescribed to him, and the list goes on. Expert testimony established that these were indicia of drug distribution. And a jury would have to blink all of this damaging evidence to conclude that Upton was just a user who blundered upon a police sting. Because a rational jury could not do so, the district court did not err in denying the lesser-included offense instructions.
D. Sentencing Enhancement
Finally, Upton argues that the district court erred in determining that Upton’s prior convictions for possessing a sawed-off shotgun and domestic battery were “violent felon[ies]” for purposes of the Armed Career Criminal Act. 2 The Armed Career Criminal Act requires a minimum sentence of fifteen years for a defendant who has “three previous convictions by any court ... for a violent felony or a serious drug offense.” 18 U.S.C. § 924(e)(1) (2006). A *404 “violent felony” consists of “any crime punishable by imprisonment for a term exceeding one year” that
(i) has as an element the use, attempted use, or threatened use of physical force against the person of another; or
(ii) is burglary, arson, or extortion, involves use of explosives, or otherwise involves conduct that presents a serious potential risk of physical injury to another;
18 U.S.C. § 924(e)(2)(B). The government offered the information or indictment for each of his convictions at sentencing. And the district court determined that they qualified 'as “violent felon[ies],” a decision we review de novo.
United States v. Blood,
On appeal, Upton challenges the district court’s conclusions with respect to two of the three prior convictions. 3 First, he argues that the government did not prove that his Illinois conviction for unlawful possession of a sawed-off shotgun qualifies because the mere possession of a sawed-off shotgun does not pose a risk of serious physical injury. Illinois law provides that “[a] person commits the offense of unlawful use of weapons when he knowingly ... possesses ... a shotgun having one or more barrels less than 18 inches in length or any weapon made from a ... shotgun ... if such a weapon as modified has an overall length of less than 26 inches.” 720 ILCS 5/24-1 (a)(7)(ii) (2007). Illinois law punishes the crime as a Class 3 felony, calling for between two and five years’ imprisonment (and meeting the federal definition of a felony). 730 ILCS 5/5— 8-1(6) (2007).
This Court has already held that the possession of a sawed-off shotgun constitutes a crime of violence for purposes of enhanced punishment under the Sentencing Guidelines,
see United States v. Brazeau,
Upton also argues that his convictions for domestic battery do not qualify. Under Illinois law, a “person commits domestic battery if he intentionally or knowingly without legal justification by any means ... [clauses bodily harm to any family or household member.” 720 ILCS 5/12 — 3.2(a)(1). An offender’s first domestic-battery conviction is a misdemeanor. But “if the defendant has any prior conviction ... for domestic battery,” it becomes a Class 4 felony, punishable by between *405 one and three years’ imprisonment. 720 ILCS 5/12 — 3.2(b); see also 730 ILCS 5/5-8-1. Upton has an unfortunate number of convictions for domestic battery (though one is too many), and he spent time in prison for three of them.
These convictions clearly qualify under the Act. In light of his recidivism, Upton’s convictions were Class 4 felonies, which allow for one to three years’ imprisonment. 730 ILCS 5/5 — 8—1(7). For all three convictions, Illinois charged Upton with committing domestic battery under 720 ILCS 5/12 — 3.2(a)(1). This provision of the statute unambiguously requires proving “physical force”: to sustain his conviction for domestic battery, the state had to prove that he “[c]ause [d] bodily harm,” which means that it had as an element “the use ... of physical force against the person of another.”
See United States v. Townsend,
III. Conclusion
In light of the forgoing, we Affirm Upton’s convictions and sentence.
