Plaintiffs-Appellants Darlie Kee and Darin Routier appeal the district court’s grant of summary judgment in favor of Defendants-Appellees the City of Rowlett, police officers Jimmy Ray Patterson and Chris Frosch, and Assistant District Attorney Greg Davis. The district court held that the placement of an electronic surveillance microphone at an outdoor grave site memorial service, which intercepted Kee and Routier’s communications, did not violate constitutional or statutory rights and therefore did not provide a predicate for their claims under 42 U.S.C. § 1983 and 18 U.S.C. § 2511. The district court reasoned that Kee and Routier failed to demonstrate that they possessed a reasonable expectation of privacy regarding their oral communications at the grave site memorial service. For the following reasons, we AFFIRM.
I. FACTUAL AND PROCEDURAL BACKGROUND
On June 14, 1996, Darlie Kee (“Kee”) and Darin Routier (“Routier”) attended a grave site memorial service for Damon Routier and Devon Routier, two minor children who were murdered on June 6, 1996 in Rowlett, Texas. Kee was the grandmother of the deceased children. Routier was the father of the deceased children. Darlie Routier, the children’s mother, was convicted of capital murder for the children’s deaths.
Jimmy Ray Patterson and Chris Frosch, police officers in the City of Rowlett (the “City”), were assigned to investigate the murders. As part of the investigation, an electronic surveillance wiretap was placed 1 in a funeral urn in close proximity to the children’s graves. The officers did not obtаin a judicial warrant or court order, nor did they obtain the family’s consent before placing the surveillance device at the grave site. However, the officers did obtain permission from the owners of the cemetery to enter and conduct their surveillance.
The grave site at issue was a privately owned plot of land situated in an outdoor and publicly accessible cemetery. The electronic surveillance device consisted of a *209 microphone planted in an urn, which recorded sounds and conversations at the grave site. The microphone recorded the surrounding sounds of the grave site for approximately fourteen hours. Police also videotaped the activities at the grave site.
Due to the notoriety of the murders and the subsequent investigation, the news media and public were aware of the planned memorial service. News reporters from local television stations and newspapers attended and observed portions of the activity at the grave site. Family members, including Kee and Routier, and other invited guests participated in services, prayers, and conversations at the grave site. The summary judgment evidence fails to detail exactly how many people attended the grave site, who was in attendance, whether there was more than one memorial service during the day, when the media observers were present, and what conversations were recorded. 2
The existence of the surveillance recordings was first discovered by Kee and Rou-tier during the capital murder trial of Dar-lie Routier. At the trial, Patterson testified to the placement of the microphone surveillance device at the grave site. Patterson also testified that the device was placed in the urn beside the grave site “[i]n case someone went up there and made a confession about what happened.” Upon learning about the existence of the surveillance recordings, Kee and Routier brought suit against those individuals and entities allegedly involved in the taping of their conversations.
The complaint sought damages, attorneys’ fees, and a declaratory judgment against Patterson and Frosch; Greg Davis, the Assistant District Attorney assigned to the case; and the City (collectively, the “defendants”). The focus of the complaint was limited to those communications and prayers directed toward the deceased children. Specifically, Kee and Routier sought damages from Patterson, Frosch, and Davis under 42 U.S.C. § 1983, alleging violations of rights under the Fourth and Fourteenth Amendments to be free from unreasonable searches and seizures, and alleging violations of the constitutional right to privacy emanating from the general protections of the First, Third, Fourth, Fifth, Ninth, and Fourteenth Amendments. Kee and Routier also sought damages under 18 U.S.C. §§ 2510-2522 3 for violation of the federal statutory law that prohibits illegally intercepting oral communications 4 without a warrant. Kee and Routier sought damages from the *210 City under 42 U.S.C. § 1983, alleging that the City failed to properly supervise and train the officers as to the apрlicable law, and that this failure was a deliberate and intentional act of indifference. Finally, Kee and Routier sought declaratory relief requesting that the actions of the defendants be declared unconstitutional.
In three separate motions, the defendants moved for summary judgment. 5 The district court held that Kee and Rou-tier had not demonstrated that they had a subjective expectation of privacy in their conversations and prayers at the grave site. Further, the district court held that even if Kee and Routier could establish a subjective expectation of privacy, the district court was not prepared to recognize this expectation as objectively reasonable. Finally, the district court found that even if Kee and Routier could demonstrate a subjective and objectively reasonable expectation of privacy, defendants were entitled to qualified immunity on the claims. Because the predicate constitutional violation could not be demonstrated, the district court dismissed all of the constitutional and statutory claims against the defendants.
Kee and Routier timely appeal the grants of summary judgment.
II. STANDARD OF REVIEW
This court reviews a grant of summary judgment de novo, viewing the evidence in the light most favorable to the nonmovant.
Smith v. Brenoettsy,
III. REASONABLE EXPECTATION OF PRIVACY
The dispositive issue in Kee and Routier’s complaint is whether the secret electronic recording of their private prayers and conversations directed at their deceased relatives violated their reasonable expectation of privacy. Their Fourth Amendment and “right to privacy” claims rest on the assumption that they had a constitutionally protected reasonable expectation of privacy regarding their oral communications at the outdoor grave site. 6 Their statutory claims, arising under 18 U.S.C. § 2511, also are predicated on enjoying a reasonable expectation of privacy in these oral communications. 7 In similar fashion, the defendants’ motions for summary judgment and defenses of qualified immunity are based on the fact that Kee and Routier cannot demonstrate that they ever possessed a reasonable expectаtion of privacy at the grave site upon which to base their constitutional and statutory claims. We approach both the constitutional and statutory claims under essentially the same analysis, asking whether Kee and Routier can demonstrate a reasonable expectation of privacy. Accordingly, our analysis necessarily focuses on this precise question. 8
A. Reasonable Expectation of Privacy in Oral Communications
“The touchstone of Fourth Amendment analysis is whether a person has a ‘constitutionally protected reasonable expectation of privacy.’ ”
California
*212
v. Ciraolo,
The district court relied on
United States v. Cardoza-Hinojosa,
Despite the differing, non-real property context of the instant case, the district court adopted the five-factor test set out in
Cardoza-Hinojosa
and applied it to the prayers and conversations at the public grave site. The
Cardozctr-Hinojosa
factors to determine an expectation of privacy include: (1) “whether the defendant has a [property or] possessory interest in the thing seized or the place searched,” (2) “whether he has a right to exclude others from that place,” (3) “whether he has exhibited a subjective expectation of privacy that it would remain free from governmental intrusion,” (4) “whether he took normal precautions to maintain privacy,” and (5) “whether he was legitimately on the premises.”
Id.
(quoting
United States v. Ibarra,
Our difficulty in applying the
Cardoza-Hinojosa
factors to oral communications is that a subjective expectation of privacy in oral communications may, but does not necessarily, turn on the physical characteristics of the place or property in which the speech takes place. In fact,
Katz
clearly shifts the constitutional protection beyond conceptions based on property to focus on the individual’s privacy interests.
See Katz,
Thus, while appropriate to determine the expectation of privacy in the context of searchеs of physical real property, the
Cardoza-Hinojosa
factors fail to engage the more difficult questions arising from oral communications, especially those communications that occur in areas accessible to the public.
See Katz,
In explicating these two factors, we are guided by analogous cases involving the reasonable expectation of privacy afforded to oral communications in the eavesdropping and wiretap contexts. Primarily, courts have looked to considerations such as (1) the volume of the communication or conversation
12
; (2) the
*214
proximity or potential of other individuals to overhear the conversation
13
; (3) the potential for communications to be reported
14
; (4) the affirmative actions taken by the speakers to shield their privacy
15
; (5) the need for technological enhancements to hear the communications
16
; and (6) the place or location of
*215
the oral communications as it relates to the subjective expectations of the individuals who are communicating.
17
We agree that these considerations help us develop, but do not define, a set of nonexclusive factors to evaluate the subjective expectation of privacy in oral communications in publicly accessible spaces.
18
See O’Connor v. Ortega,
B. The Failure to Demonstrate Sufficient Facts to Establish a Subjective Expectation of Privacy
Under the summary judgment standard, Kee and Routier must demonstrate that a genuine issue of material fact exists as to their reasonable expectation of privacy in their oral communications. “Although we consider the evidence and all reasonable inferences to be drawn therefrom in the light most favorable to the
*216
nonmovant, the nonmoving party may not rest on the mere allegations or denials of its pleadings, but must respond by setting forth specific facts indicating a genuine issue for trial.”
Rushing v. Kansas City Southern Ry. Co.,
In their affidavits, Kee and Routier assert that their “grieving conversations and statements” and “oral prayers and communications to ourselves and our God” should be private and not subject to government wiretaps. These statements, alone, cannot sustain the weight of Kee and Routier’s burden in establishing that they had a subjective expectation of privacy.
See Lawrence v. Univ. of Tex. Med. Branch,
For example, Kee and Routier adduced no evidence regarding the context of the communications that they now seek to characterize as private. They do not argue that the prayers were hushed or that their voices were modulated to protect their conversations from “uninvited ears,” and they have provided no information about the tone, volume, or audibility of the private communications directed toward the graves. They do not specify which conversations were conducted in a manner inaudible to others and provide no information about who was present and to whom their conversations were directed. As knowledge of these important facts is well within the control of Kee and Routier, the failure to include this information in their affidavits undermines any claim of an expectancy of privacy.
In similar fashion, Kee and Routier do not assert that their oral statements were communicated free from the possibility of eavesdroppers who might have been in close proximity to the grave site. In fact, the defendants have submitted evidence to demonstrate that the grave site services were attended by representatives of the media and that third parties were in close proximity to the grave site. Kee and Rou-tier simply fail to respond to this argument that рotentially would eviscerate a subjective expectation of privacy. Furthermore, they provide us with no particularized information regarding their activities vis-a-vis the other people known to be at the cemetery and, thus, fail to provide information necessary to find that they had a subjective expectation of privacy. 19
Perhaps most damaging to Kee and Routier’s argument is that they failed to present evidence demonstrating any affirmative steps taken to preserve them privacy. While it is apparent from their affidavits that they did not expect government agents surreptitiously to be recording their prayers, they also were aware that the service was being conducted in an outdoor setting. Kee and Routier fail to allege that they took any steps to ensure that unwanted individuals were excluded or that they did anything to preserve the private nature of the service. They point to no reasonable safeguards or common *217 sense precautions taken to preserve their expectation of privacy.
The strongest argument presented by Kee and Routier is that the surveillance was accomplished through the use of technological enhancements. This is a case in which the information possibly was not audible to the “unaided ear.”
See United States v. Jackson,
Finally, Kee and Routier provide almost no information regarding the physical layout or location of the grave site where the prayers or conversations took place. For example, no information is provided about the privately owned burial plot in relation to the rest of the cemetery. Kee and Routier have presented no information regarding the grave site’s proximity to the entrance of the cemetery, or regarding whether the public was prevented from accessing the grave site or whether the grave site was secluded by other graves or natural objects, such as trees or bushes. In contrast, the defendants assert that the conversations took place in the open air of a publicly accessible cemetery and that there were no barriers to prevent individuals, such as the assembled media and onlookers, from observing the activities. 21 Again, Kee and Routier have failed to meet their summary judgment burden to demonstrate that an issue of material fact exists as to whether their subjective expectation of privacy was violated.
Because we agree with the district court that no subjective expectation of privacy was established on the facts presented, we affirm the grants of summary judgment. As such, we do not reach the question whether individuals such as Kee or Routier *218 could have an objectively reasonable expectation of privacy at a grave site burial service under different facts or whether the individual defendants would have qualified immunity in such a situation. Further, because our holding rests on Kee and Routier’s failure to demonstrate their subjective expectation of privacy, we do not reach the question whether, in other сircumstances, officers would be required to obtain judicial approval for a wiretap pursuant to 18 U.S.C. § 2511.
IV. CONCLUSION
For the foregoing reasons, we AFFIRM the judgment in favor of all defendants.
Notes
. There is some discrepancy in the record regarding whether Patterson and Frosch were directly responsible for the actual placing of the wiretap in this location. Both Patterson and Frosch state, in their affidavits submitted in support of their summary judgment motion, that they were aware of the investigation into the Routier children's murder. Both claim, however, that they had circumscribed roles in the direct surveillance activities. In contrast, Kee and Routier allege that Patterson admitted under oath in the state criminal trial of Darlie Kee that he was the lead investigator on thе case and that he was involved in planning the surveillance. Furthermore, Kee and Routier point to Frosch's affidavit in which he admitted to obtaining an urn from the cemetery owners, which he understood would be used in the surveillance. Frosch also admitted to discussing the surveillance with the owners of the cemetery.
The district court did not determine the extent of Patterson and Frosch's involvement, finding that even if Patterson and Frosch were involved in the surveillance, no constitutionally significant expectation of privacy was violated. We proceed in similar fashion.
. Because the district court stayed discovery until the qualified immunity issues were determined, the factual record is limited.
. Kee and Routier claimed a violation of 18 U.S.C. § 2511. Section 2511 provides in relevаnt part: “(1) Except as otherwise specifically provided in this chapter any person who[:] (a) intentionally intercepts, endeavors to intercept, or procures any other person to intercept or endeavor to intercept, any wire, oral, or electronic communication ... shall be punished ... or shall be subject to suit.” 18 U.S.C. § 251 l(l)(a.) (2000).
In general, Title III of the Omnibus Crime Control and Safe Streets Act of 1968, as amended by the Electronic Communications Privacy Act of 1986 ("Federal Wiretap Act"), "has as its dual putpose (1) protecting the privacy of wire and oral communications, and (2) delineating on a uniform basis the circumstances and conditions under which the interception of wire and oral communications may be authorized.”
Forsyth v. Barr,
.Section 2510 defines "oral communication” as "any oral communication uttered by a person exhibiting an expectation that such communication is not subject to interception under circumstances justifying such expectation, but such term does not include any electronic communication.” 18 U.S.C. § 2510(2).
. Patterson and Frosch moved for summary judgment on the ground that Kee and Routier had failed to demonstrate that a constitutional right had been violated. In the alternative, Patterson and Frosch invoked qualified immunity, arguing that no reasonable police officer would have believed that the officers’ actions would have violated the constitutional rights of Kee and Routier.
Davis moved for summary judgment on the ground that Kee and Routier could not allege an actionable federal claim against him personally, because they could not directly connect him to supervising or administering the electronic surveillance. Davis also invoked absolute and qualified immunity because he alleged his actions were taken pursuant to his prosecutorial duties.
The City moved for summary judgment on the ground that Kee and Routier could not demonstrate that they had a constitutionally protected reasonable expectation of privacy and that Kee and Routier could not demonstrate that the City maintained a policy, practice, or custom that authorized its police officers to violate the reasonable expectation of privacy of its citizens.
. Specifically, Kеe and Routier’s complaint alleges violations of the Fourth and Fourteenth Amendments: "The Fourth and Fourteenth Amendments protect Plaintiffs from Defendants’ unlawful search and seizure. The conduct of Defendants infringes upon the Plaintiffs' personal liberty and privacy rights."
In addition, they allege infringement of their right to privacy under the First, Third, Fourth, Fifth, Ninth, and Fourteenth Amendments: "The Constitution of the United States protects the Plaintiffs from the Defendants indiscriminate invasion in both their conduct and in their speech. The rights of Plaintiffs to grieve and mourn the loss [of] their close relatives at a grave site service raises very dear and close personal matters which are private and which involve family relationships and are thus protected. The Plaintiffs had a reasonable expеctation of privacy during the private grave site funeral and prayer services for Damon and Devon Routier which was violated, without warrant or court order, by the Defendants’ conduct described herein.”
. Kee and Routier’s complaint alleges "the conduct of the Defendants as described [in the complaint] constitutes a violation of 18 U.S.C.A. § 2511, et. seq., chapter 119 — Wire and Electronic Communications Interception and Interception of Oral Communications as set forth in Title 119 of the United States Code Annotated. The Defendants' conduct as described herein is an unlawful interception and/or disclosure of an oral communication as prohibited by 18 U.S.C.A. § 2511, et. seq." We note that the district court did not specifically address Kee and Routier’s § 2511 claims.
.In the instant case, the Fourth Amendment determination of a reasonable expectation of privacy and the federal wiretap analysis overlap. 18 U.S.C. § 2510(2) protects oral communications "uttered by a person exhibiting an expectation that such communication is not subject to interception under circumstances justifying such expectation.” 18 U.S.C. § 2510(2). The legislative history of this section demonstrates that Congress intended this definition of oral communication to parallel the reasonable expectation of privacy test set out in
Katz v. United States,
.
Katz
involved a factual situation in which government agents eavesdropped on conversations in a telephone booth by means of an electronic listening device attachеd to the top of the booth.
See
. Like
Cardoza-Hinojosa, Ibarra
involved the question whether defendants had standing to contest the search of a physical structure, specifically a house.
See Ibarra,
. Applying the Cardoza-Hinojosa factors to the factual situation in Katz demonstrates the appropriateness of this shift in emphasis. For example, Katz had a negligible property or possessory interest in the telephone booth; did not have an enforceable right to exclude others from the property; and while legitimately on the premises, did not gain an expectation of privacy from that position. Instead, the constitutional protections stemmed from the fact that he subjectively expected his conversations to be private and that he took the normal precautions available to him to call from inside a boоth.
.
See, e.g., United States v. Smith, 91 &
F.2d 171, 177 (5th Cir.1992) (citing
United States v. Burns,
.
See, e.g., In re John Doe Trader Number One,
.
See, e.g., United States v. White,
.
See, e.g., Katz,
.
Compare Jackson,
The Court in
Katz
recognized this tension. On one hand Justice Harlan explained that persons having "conversations in the open could not be protected from being
overheard,”
but that same person holding a conversation in a telephone booth did have a reasonable expectation not to have that conversation electronically "intercepted.”
See Katz,
.
See, e.g., Minnesota v. Carter,
. Therefore, as was discussed in oral argument, while two federal judges may have a reasonable expectation of privacy in a hushed conversation on the courthouse steps, they might lose that expectation of privacy if they spoke loudly, if they were surrounded by people who could eavesdrop, if one of the judges reported the conversation to authorities, if either party otherwise took actions that would expose the confidentiality of their communications, or if they failed to take any affirmative steps to shield their privacy.
. Following the nonexclusive factors set out in Part III.A, we note that there is no allegation that anyone at the grave site service reported the incident to authorities. This consideration is, therefore, irrelevant to our analysis.
. See supra note 16.
. The fact that the prayers and conversations took place in an outdoor publicly accessible space is a difficult hurdle for Kee and Routier to overcome. While neither party briefed the issue, we note a possible overlap between the "open fields” doctrine, which is well-established in Fourth Amendment jurisprudence and the instant case. However, the open fields doctrine has not been expanded beyond observational searches.
