United States v. Williams

Citations: 161 F. Supp. 3d 846; 2016 U.S. Dist. LEXIS 16442; 2016 WL 492933Docket: Case No. 13-cr-00764-WHO

Court: District Court, N.D. California; February 8, 2016; Federal District Court

Narrative Opinion Summary

The case involves defendants A. Gilton and B. Gilton, who sought to suppress cell phone data obtained through warrants and an exigent request in the context of a police investigation into a shooting. The primary legal issues concern the Fourth Amendment's protection against unreasonable searches and seizures, the application of the exclusionary rule, and the doctrines of good faith and inevitable discovery. A. Gilton's data from a Sprint warrant was suppressed due to a lack of probable cause in the supporting affidavit, and the good faith exception was deemed inapplicable as the government failed to demonstrate a colorable argument for probable cause. The inevitable discovery doctrine also did not apply because the government could not show that the evidence would have been discovered lawfully. Conversely, B. Gilton's motions to suppress data obtained through an exigent request and a T-Mobile warrant were denied. The court found that even if the exigent request was improper, the affidavit for the T-Mobile warrant, purged of unlawfully obtained information, still established probable cause. The outcome led to the suppression of evidence against A. Gilton but not against B. Gilton, based on the sufficiency of the probable cause and the expectations of privacy relating to their cell phone data.

Legal Issues Addressed

Exigent Circumstances and Affidavit Purging

Application: In B. Gilton's case, even if the exigent request was unjustified, the T-Mobile warrant affidavit, once purged of unlawfully obtained information, still supported probable cause.

Reasoning: Even assuming the exigent request was improper, the T-Mobile warrant affidavit still provided a substantial basis for probable cause, supported by an anonymous informant’s detailed tip regarding a related shooting incident.

Fourth Amendment and Probable Cause

Application: The Fourth Amendment requires that warrants be based on probable cause. In this case, A. Gilton's motion to suppress the Sprint warrant data was granted due to the affidavit's lack of sufficient detail to establish probable cause.

Reasoning: Regarding probable cause for the Sprint warrant, the standard requires a fair probability that evidence of a crime will be found, but the supporting affidavit for Gilton's cell phone records lacked sufficient detail.

Good Faith Exception

Application: The good faith exception to the exclusionary rule was not applicable in A. Gilton's case because the affidavit lacked probable cause, negating reasonable reliance by law enforcement.

Reasoning: The government's argument for the good faith reliance exception was unconvincing, as there was no substantial evidence linking Gilton to the crime...

Inevitable Discovery Doctrine

Application: The government failed to show that the evidence seized would have been inevitably discovered through lawful means, as required for the doctrine's application.

Reasoning: The inevitable discovery doctrine permits the admission of evidence if it can be shown that the evidence would have been discovered inevitably...In this case, the government failed to demonstrate that the situation warranted the application of this doctrine.

Reasonable Expectation of Privacy in Cell Site Location Information (CSLI)

Application: A. Gilton was found to have a reasonable expectation of privacy in his historical CSLI, leading to the suppression of evidence obtained from the Sprint warrant.

Reasoning: A. Gilton had a reasonable expectation of privacy regarding his historical Cell Site Location Information (CSLI), as established by recent judicial rulings...
