2026“The exclusionary rule is not a personal constitutional right; nor is it designed to ‘ “redress the injury” occasioned by an unconstitutional search.’ [Citations.] It is ‘ “a judicially created remedy designed to safeguard Fourth Amendment rights” ’ by deterring ‘police misconduct’ rather than by punishing ‘the errors of judges and magistrates.’ (United States v. Leon (1984) 468 U.S. 897, 906, 909, 916 (Leon); see Herring v. United States 13 The opening brief appears to argue that the lack of time and date limitations on the video surveillance to be seized made the warrant both insufficiently

2026(United States v. Leon (1984) 468 U.S. 897, 906 .) However, the Supreme Court has held that the exclusionary rule does not apply to evidence obtained by the police when they acted in objective reasonable reliance on a valid search warrant issued by a neutral magistrate, even if the warrant was later found to be unsupported by probable cause.

2021To say that no warrant is required is merely to acknowledge that ‘rather than employing a per se rule of unreasonableness, we balance the privacy-related and law enforcement- related concerns to determine if the intrusion was reasonable.’ This application of ‘traditional standards of reasonableness’ requires a court to weigh ‘the promotion of 19 legitimate governmental interests’ against ‘the degree to which [the search] intrudes upon an individual’s privacy.’ ” (King, supra, 569 U.S. at p. 448 .)

2026(Wong Sun v. United States (1963) 371 U.S. 471 , 486-487 [defendant’s statements after unlawful arrest excluded].) And although the Attorney General suggests that Perez’s in-field identification by the reporting party should not be excluded, the exclusionary rule applies to that kind of evidence as well.

2025Applicable Law The Fourth Amendment protects the “right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures.” (U.S. Const., 4th Amend.) “ ‘A warrantless search is presumed to be unreasonable, and the prosecution bears the burden of demonstrating a legal justification for the search [or seizure].’ ” (People v. Suff (2014) 58 Cal.4th 1013, 1053 .) “If the prosecution cannot meet this burden, the exclusionary rule normally requires the suppression of any evidence obtained from the search or seizure.” (People v.

2026Under the exclusionary rule, the evidence seized due to 6 Perez’s illegal seizure must be suppressed.4 (Davis v. United States (2011) 564 U.S. 229, 232 .) The parties agree that if Perez’s detention was unconstitutional, all evidence seized on his person must be suppressed.

2025(Herring, supra, 555 U.S. at p. 141 .) As the Court explained: “ ‘[T]o the extent that application of the exclusionary rule could provide some incremental deterrent, that possible benefit must be weighed against [its] substantial social costs.’ [Citation.] The principal cost of applying the rule is, of course, letting guilty and possibly dangerous defendants go free—something that ‘offends basic concepts of the criminal justice system.’ [Citation.] ‘[T]he rule’s costly toll upon truth-seeking and law enforcement objectives presents a high obstacle for those urging [its] application.’ ” (Ibid.)

2023The lives and safety of police officers weigh heavily in the balance of competing Fourth Amendment considerations.” (Dickey, supra, 21 Cal.App.4th at p. 957 .) However, we are equally mindful that the exclusionary rule serves the vital purpose of “compel[ling] respect for the constitutional guaranty [of the Fourth Amendment] in the only effectively available way—by removing the incentive to disregard it.” (Elkins, supra, 364 U.S. at p. 217 ; see People v. Sanders (2003) 31 Cal.4th 318, 334 .) Thus, in implementing the rule in this case, we do so to reemphasize that a pat search “is a serious i

2023Its purpose is to deter—to compel respect for the constitutional guaranty in the only effectively available way—by removing the incentive to disregard it.” (Elkins v. United States (1960) 364 U.S. 206, 217 (Elkins).) In our view, the substantial lack of justification for the pat search, the close connection between the illegal pat search and the discovery of the drug evidence, and the lack of any exigency or emergency, warrants 22 application of the exclusionary rule.

2024(Krull, supra, 480 U.S. at p. 347 .) “To trigger the exclusionary rule, police conduct must be sufficiently deliberate that exclusion can meaningfully deter it, and sufficiently culpable that such deterrence is worth the price paid by the justice system.

2024The Exclusionary Rule and Good Faith Exception “[T]he exclusionary rule generally bars admission of the evidence seized that was beyond the scope of the warrant.” (United States v. Sedaghaty (9th Cir. 2013) 728 F.3d 885, 915 (Sedaghaty).) It is a “judicially created rule [that] is ‘designed to safeguard Fourth Amendment rights generally through its deterrent effect’ ” (Herring v.

Gray v. Zurich Insurance Co.green

2016To be sure, Mullen held that “injuries resulting from acts committed by an insured in self-defense”—“even if [the insured] exceeded the reasonable bounds of self- defense”—“are not ‘intended’ or ‘expected’ within the meaning of those terms as 8 customarily used in an exclusionary clause.” (Id. at pp. 170-171; see also Gray v. Zurich Insurance Co. (1966) 65 Cal.2d 263, 277 [same].) But Mullen and Gray—the decision on which Mullen relies—were interpreting an exclusion to an insurance policy, not the policy’s coverage in the first place.

2007(Id. at pp. 514-516.) Our statement with regard to such a choice-of-law decision by a California court concerned the enforceability of an express contractual promise, rather than contract interpretation. 19 Moreover, the pollution liability endorsement here expressly states that it “forms a part of the policy to which attached.” 20 Gray, supra, 65 Cal.2d at page 274 , stated: “Since we must resolve uncertainties in favor of the insured and interpret the policy provisions according to the layman’s reasonable expectations, [fn. omitted] and since the effect of the exclusionary clause is neither

2024(See Leon, supra, 468 U.S. at p. 924 ; People v. Camarella, supra, 54 Cal.3d at p. 596 .) Because Detective Armando’s belief that the affidavit presented probable cause to search Lopez’s cell phone records was not objectively unreasonable, the Leon exception to the exclusionary rule applies, and the motion to quash was properly denied.7 DISPOSITION The judgment is affirmed. 7 By reason of this holding, there is no need to address Lopez’s argument that all of the evidence obtained from the subsequent July 2014 search warrant should be excluded as fruit of the poisonous tree. 25 ________________

2023“The fact that a Fourth Amendment violation occurred—i.e., that a search or arrest was unreasonable—does not necessarily mean that the exclusionary rule applies.” (Herring v.

Leon (1984) 468 U.S. 897, 922 (Leon).) “When police act under a warrant that is invalid for lack of probable cause, the exclusionary rule does not apply if the police acted ‘in objectively reasonable reliance’ on the subsequently invalidated search warrant.” (Herring, at p. 142; Leon, at p. 922.)

Brendlin (2008) 45 Cal.4th 262, 271 .)

Brendlin (2008) 45 Cal.4th 262, 271 .) The first two factors, as the People concede, do not support finding attenuation: Seto’s consent to search the residence immediately followed the pat search, with no temporal separation and no intervening circumstance.

Finally, the third Brown factor—generally regarded as “the most important” because of its direct tie to the exclusionary rule’s 10 purpose of deterring police misconduct (Brendlin, supra, 45 Cal.4th at p. 271 )—also counsels against suppression. “[T]here is no indication” that Kay’s detention “was part of any systemic or recurrent police misconduct.” (Utah v. Strieff (2016) 579 U.S. 232, 242 .) To the contrary, officers detained Kay to permit them to investigate “what was happening inside a house whose occupant[ ] [was] legitimately suspected” of wrong

2017Though there is little, if any, concern that expert witnesses would commit perjury, 8 the admission of this evidence prevents the defendant from turning the exclusionary rule into a “ ‘a shield against contradiction of his untruths.’ ” (Harris, supra, 401 U.S. at p. 224 , quoting Walder, supra, 347 U.S. at p. 65 .) Nor would the admission of the suppressed statements have a chilling effect on a defendant’s ability to present a defense.

The court explained that the benefit to the jury of evaluating the defendant’s credibility in light of prior inconsistent statements should not be lost, and that, assuming the exclusionary rule has the effect of deterring police misconduct, there was sufficient deterrence when the prosecution is barred fro

2014The Trial Court Did Not Err By Denying the Motion to Suppress The Fourth Amendment to the United States Constitution “‘proscribes all unreasonable searches and seizures’” (Robey v. Superior Court (2013) 56 Cal.4th 1218, 1224 ) “‘to safeguard the privacy and security of individuals against arbitrary invasions by government officials’” (People v. Banks (1993) 6 Cal.4th 926, 934 ). “‘Under the Fourth Amendment, a[] [judicial] officer may not properly issue a warrant to search a private dwelling unless he can find probable cause therefor[e] from facts or circumstances presented to him under oath o

In the aftermath of this still-continuing *146 judicial return to reason, peace officers and their agencies would be mistaken to assume they may seek haven in the good faith exception to the exclusionary rule, for example, and there find a license to be casual or, worse, careless.

2024(Id. at pp. 995-996.) The court held that “the search warrants were written with sufficient particularity because the items listed on the warrants were qualified by phrases that emphasized that the items sought were those related to child pornography,” and thus, “[p]olice officers executing the warrants were not unguided and free to rummage through Hall’s property.” (Id. at pp. 996-997, fn. omitted.) 33 “Exclusion of evidence due to a Fourth Amendment violation is not automatic.” (People v.

2023Balancing the benefits of the exclusionary remedy against its costs, the United States Supreme Court has fashioned various exceptions to the exclusionary rule, including the so-called attenuation doctrine. ( Strieff, supra, 579 U.S. at pp. 237–238; see Davis, supra, 564 U.S. at p. 237 .) The attenuation doctrine holds that, notwithstanding the exclusionary rule, “[e]vidence is admissible when the connection between unconstitutional police conduct and the evidence is remote or has been interrupted by some intervening circumstance, so that ‘the interest protected by the constitutional guarantee
