William Bernal v. Sacramento County Sheriff's Department, 73 F.4th 678

Background

On March 5, 2018 deputies investigated credible threats that high‑schooler Ryan Bernal texted an intent to "shoot up the school" that day; Celia (mother) told a deputy by phone Ryan was at his grandmother’s but would not give the address over a blocked number.
Six uniformed Sacramento County deputies went to the Bernal home to locate Ryan; they intended briefly to detain Celia and William (parents) as non‑suspect witnesses to obtain Ryan’s location.
Celia ignored orders to stay out of and then exit her car; deputies used control holds (a twist‑lock) to prevent her from leaving, did not handcuff her, and seated her in the yard.
William placed a duffel bag on the car hood; the parties dispute whether he reached into it or instead held up his cell phone to record and yelled. Deputies quickly recognized the object was a phone but proceeded to draw weapons, forcefully restrain him, and handcuff him, causing injury.
The encounter lasted about 20 minutes; deputies then confirmed Ryan’s location, led to his arrest, and Ryan later pleaded no contest to a misdemeanor threats charge.
The district court granted summary judgment for the deputies on Fourth Amendment and qualified immunity grounds; the Ninth Circuit affirmed as to Celia and the seizure issue but reversed as to William’s excessive‑force claim and denied qualified immunity for that claim, reinstating pendent state claims.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
1) May police briefly detain non‑suspect witnesses without reasonable suspicion to obtain time‑sensitive information about an imminent school shooting?	Bernal: Deputies lacked individualized suspicion; suspicionless detentions are generally unconstitutional.	Deputies: Exigent public‑safety emergency (imminent school shooting) and witness confirmation of location justified brief, suspicionless detention.	Held: Yes, narrowly. Exigency and witness knowledge (location of suspected shooter) justified a limited, minimally intrusive detention here (≈20 minutes).
2) Was force used on Celia excessive?	Bernal: Holding Celia’s arms and using a twist‑lock was excessive for a non‑suspect.	Deputies: Minimal, control holds after warnings were reasonable to prevent flight during exigent investigation.	Held: No. Force was minimal, proportional, and reasonable under Graham factors; summary judgment for deputies affirmed as to Celia.
3) Was force used on William excessive?	Bernal: Deputies used significant force (weapons drawn, head smashed to hood, kicked/forced knees, tight handcuffs) though he was unarmed and either recording or only minimally resisting.	Deputies: William reached into a bag (possible weapon), resisted, and was large relative to deputies; force was necessary for officer safety and to effect detention/arrest.	Held: Yes. Disputed material facts (did he reach into bag?) and the undisputed fact that deputies quickly saw a phone make the force excessive; summary judgment reversed for William.
4) Are deputies entitled to qualified immunity for William’s excessive‑force claim?	Bernal: Force violated clearly established Fourth Amendment and First Amendment rights (recording/verbal criticism); qualified immunity inapplicable.	Deputies: No clearly established precedent on these particular facts; reasonable officers could have believed force lawful.	Held: No immunity. Existing precedent made it clearly established that (a) recording/verbally challenging police is protected and (b) reaching into an unsearched bag, without other indicia of a weapon, does not justify violent force.
