8 Plaintiffs, ORDER REGARDING DISCOVERY 9 v. LETTER BRIEFS

10 CITY AND COUNTY OF SAN Re: Dkt. Nos. 58, 59, 74 FRANCISCO, et al., 11 Defendants.

12 14 This case concerning an alleged mass arrest (or detention)1 following the Dolores Hill 15 Bomb, an unsanctioned skateboarding event, in the summer of 2023. Plaintiffs J.T., L.R., and 16 C.L. are three minors who were arrested. Defendants are the City and County of San Francisco 17 and three of its police officials. This Order resolves three joint letters raising discovery disputes. 18 ECF Nos. 58, 59, 74.2 19 This Order is captioned for—and primarily concerns—Case No. 23-cv-06524, which is the 20 case where the parties filed all of the letter briefs at issue. The plaintiff in a related case, R.P. v. 21 City & County of San Francisco, No. 24-cv-00522, also joined in at least one of the letter briefs 22 resolved here. See ECF No. 59 at 6. The Clerk is therefore instructed to file a copy of this Order 23 in that case as well. This Order will apply in Case No. 24-cv-00522 with respect to any discovery 24 dispute where Plaintiff R.P.’s attorneys signed the joint letter filed with the Court or consented to 25 1 The Court recognizes that California law, in at least some circumstances, specifically avoids 26 using the word “arrest” to describe the police detention of minors. This Order uses that term in its colloquial sense, without resolving any question of whether the events at issue constituted 27 “arrests” under state law. 1 the filing of the joint letter on R.P.’s behalf. Going forward, the parties are instructed to file 2 copies in both cases of any documents that seek relief in both cases or otherwise pertain to both 3 cases. 5 A. The Parties’ Disputes that Relate to the Preservation of Relevant Evidence 6 “As soon as a potential claim is identified, a litigant is under a duty to preserve evidence 7 which it knows or reasonably should know is relevant to the action.” In re Napster, Inc. 8 Copyright Litig., 462 F. Supp. 2d 1060, 1067 (N.D. Cal. 2006). The duty to preserve evidence 9 “includes an obligation to identify, locate, and maintain information that is relevant to specific, 10 predictable, and identifiable litigation.” Apple v. Samsung Elecs. Co., Ltd., 881 F. Supp. 2d 1132, 11 1137 (N.D. Cal. 2012). The duty to preserve information pertains only to relevant records. Id. 12 As noted above, this case concerns a mass arrest by SFPD following the Dolores Hill 13 Bomb, and Plaintiffs have alleged that Defendants violated their rights and the rights of the 14 putative class under the Fourth Amendment of the U.S. Constitution. Specifically, Plaintiffs 15 allege that Defendants lacked the necessary justification to institute a mass arrest.3 Under Ninth 16 Circuit precedent, however, “[i]f a group or crowd of people is behaving as a unit and it is not 17 possible . . . for the police to tell who is armed and dangerous or engaging in criminal acts and 18 who is not,” the police are authorized to detain the members of the group if there is probable cause 19 to believe that the group violated the law. Lyall v. City of Los Angeles, 807 F.3d 1178, 1194 (9th 20 Cir. 2015). The key question is whether the officer’s belief at the time “was reasonable in light of 21 the circumstances.” Id. The existence of probable cause to make a lawful warrantless arrest is 22 determine based on “the totality of the circumstances known to the arresting officers” and 23 considers whether “officers have knowledge or reasonably trustworthy information sufficient to 24 lead a person of reasonable caution to believe that an offense has been committed or is being 25 committed by the person[s] being arrested.” United States v. Lopez, 482 F.3d 1067, 1072 (9th Cir. 26 2007). In this case, in particular, a central question will likely be whether Defendants had a 27 1 reasonable belief that the group of individuals detained had some connection with individuals who 2 allegedly damaged property earlier in the evening at a different, but nearby location. See 3 Corrected Am. Compl., ¶ 76. 4 With these considerations in mind, the Court addresses the parties’ disputes regarding their 5 preservation obligations. 6 1. Defendants’ Teams Messages 7 Plaintiffs raised concerns that Defendants had not taken steps to secure messages sent and 8 received by SFPD employees using Microsoft Teams concerning the Dolores Hill Bomb. ECF 9 No. 58 at 1–2. After arguments from both sides concerning this issue, Defendants filed a status 10 report indicating that they had identified and preserved relevant Teams messages. ECF No. 62. 11 The record before the Court does not indicate that relevant messages were lost in the intervening 12 period before Defendants identified and preserved those messages. The Court understands this 13 issue to be resolved, and does not reach the parties’ arguments as to when the duty to preserve 14 such messages attached. 15 2. Preservation of Plaintiffs’ Devices 16 a. The Named Plaintiffs’ Smartphones 17 The parties first raised a dispute concerning preservation of Plaintiffs’ mobile devices in a 18 case management statement and in argument at a case management conference, and the Court 19 issued an Order on May 2, 2024 that included the following instructions regarding mobile devices:

20 As for Plaintiffs’ obligations, the Court rejects Plaintiffs’ apparent position that only Defendants’ evidence is relevant to this case. If 21 Plaintiffs proceed on a claim for arrest without probable cause, evidence of their location and activities (which might include location 22 data, photographs, videos, or messages describing such activities) may be relevant to resolve any conflicts between Defendants’ and 23 Plaintiffs’ accounts of what Defendants observed on the night in question. If Plaintiffs proceed on claims based on conditions of 24 confinement or excessive force, there may be relevant evidence in the form of messages Plaintiffs sent describing such conditions or force, 25 either during their confinement or after the fact. (These examples are intended to be illustrative rather than comprehensive.) 26 In light of the wide variety of potential evidence contained in a 27 smartphone, and the risks inherent in trusting the retention of such each named Plaintiff’s phone to be reasonable and proportional to the 1 needs of the case. The Court has not reached a conclusion as to whether forensic imaging is necessary or if commercial backup 2 software might be sufficient. The parties to both cases shall meet and confer in person or by videoconference to identify a specific process 3 to preserve data from Plaintiffs’ smartphones, and file no later than May 10, 2024 either a joint statement identifying an agreed process 4 or a discovery letter brief setting forth their respective positions. 5 ECF No. 56 at 4. 6 The parties did not reach an agreement and instead filed a joint letter. Plaintiffs do not 7 propose any “specific process to preserve data from [their] smartphones” as required by the 8 Court’s previous Order. ECF No. 56 at 4. Instead, they assert:

9 Plaintiffs have preserved relevant text messages, photos and videos taken during the events in question. Unfortunately, unbeknownst to 10 counsel, two of the children in the J.T. case got new phones prior to the filing of this lawsuit, and did not keep their old phones, which 11 were not backed up. However, pertinent communications and images have been preserved and can be produced.
