Excessive Force
Excessive Force in Custody: Three Different Legal Standards, and Why It Matters Which One Applies
Every week we hear the same phrase from families and from people writing to us from inside: "they used excessive force." It's the right instinct, but the law doesn't treat "excessive force" as a single question. Which constitutional standard applies — and how hard your case is to prove — depends entirely on your custodial status at the moment the force was used. Knowing which lane you're in changes everything about how the claim should be built.
Three statuses, three standards
If you were a free citizen being arrested or stopped: the Fourth Amendment's "objective reasonableness" standard applies. The Supreme Court set this rule in Graham v. Connor, 490 U.S. 386 (1989), holding that claims of excessive force during an arrest, investigatory stop, or other seizure are judged by whether the officer's actions were objectively reasonable in light of the facts confronting them — not by the officer's underlying intent. The Court weighs the severity of the alleged crime, whether the suspect posed an immediate threat, and whether the suspect was resisting or fleeing, all from the perspective of a reasonable officer on the scene, not with 20/20 hindsight.
If you were a pretrial detainee — arrested and held, but not yet convicted of anything — the Fourteenth Amendment's Due Process Clause governs, and the standard is also purely objective. In Kingsley v. Hendrickson, 576 U.S. 389 (2015), the Supreme Court held that a pretrial detainee need only show the force used against them was objectively unreasonable; there is no need to prove what was in the officer's head. The Court listed several factors that bear on reasonableness — the relationship between the need for force and the amount used, the extent of any injury, whether officers tried to temper the response, and the severity of the security problem they were facing — while making clear that list isn't exhaustive.
If you were a convicted prisoner, the standard shifts again — and gets harder. The Eighth Amendment's ban on cruel and unusual punishment applies, and under Hudson v. McMillian, 503 U.S. 1 (1992), the question is not objective reasonableness at all. It's whether the force was applied "in a good-faith effort to maintain or restore discipline" or "maliciously and sadistically to cause harm" — the standard first articulated in Whitley v. Albers, 475 U.S. 312 (1986). That's a subjective inquiry into the officer's state of mind, and it's a meaningfully higher bar than what a pretrial detainee or free citizen has to clear.
Why this actually matters for your case
One consequence worth understanding: under Hudson, a convicted prisoner does not need to show a "significant injury" to have a viable Eighth Amendment claim. The Court was explicit that when force is used maliciously and sadistically, "contemporary standards of decency are always violated" — even where the physical injury was comparatively minor. What matters is whether the force was necessary at all, not just how much damage it left behind. Too many people assume no visible injury means no case. That's not the legal rule, though it does affect how persuasive the evidence is to a jury.
The other practical consequence: your status can change during the same encounter. Someone tackled and handcuffed by responding officers, then further restrained after being formally booked, may have facts that span more than one standard. Sorting out exactly when custody status changed — and which standard applies to which specific moment of force — is exactly the kind of analysis that belongs in an intake review, not a guess.
What builds a strong excessive force case regardless of which standard applies
Whichever standard governs, the same categories of evidence matter:
- Contemporaneous records — incident reports, use-of-force reports, body camera or facility camera footage, medical intake records documenting injuries
- Witness accounts — other detainees, visitors, or staff who saw what happened, gathered while memories are fresh
- Your own written account — dated and detailed, created as soon as possible after the incident
- Grievance records, if the incident happened in custody — courts can dismiss a strong claim before reaching the merits if the facility's grievance process wasn't fully exhausted first
If you or someone you love was hurt by force that shouldn't have been used, the first step isn't figuring out which legal standard applies yourself — it's getting the facts in front of people who do this every day.
