The use of force in prisons is lawful only when it serves a legitimate security purpose, is proportional to the threat, stops the moment the threat ends, and is documented and medically reviewed afterward. Federal law and Bureau of Prisons policy spell out when officers may put hands on someone, when they must pause and plan first, what tactics are off-limits, and what has to happen on paper and on video once the incident is over. Convicted prisoners are protected by the Eighth Amendment; people held before trial get a stricter protection under the Fourteenth. Both can sue, but both face real obstacles.
When Officers Are Allowed to Use Force
Physical intervention is permitted when someone faces an immediate threat to life or safety. Self-defense is the clearest justification: if an incarcerated person attacks a staff member, force to stop the assault is lawful. The same applies to defending other inmates or staff during an altercation, and to preventing escapes or serious property destruction.
Force may also be used to compel compliance with a lawful order when safety is on the line. If an inmate refuses to return to a cell during a lockdown, chemical or mechanical intervention may be authorized to restore order. The level of force has to match the level of resistance and the seriousness of the threat. More than that is excessive.
Immediate Force
When a situation demands instant action, officers can respond without waiting for supervisor direction. Federal Bureau of Prisons policy authorizes immediate force when an inmate is attempting life-threatening self-harm, assaulting another person, or causing serious property destruction that cannot wait.1Federal Bureau of Prisons. Program Statement 5566.07 – Use of Force, Application of Restraints, and Firearms Staff must grab a camera and begin recording as soon as feasible, even if recording was not possible at the very start of the confrontation.
Calculated (Planned) Force
When the inmate is isolated and poses no immediate threat, the Bureau of Prisons requires a deliberate, multi-step process before anyone enters the cell. Staff must first try to resolve the situation through verbal negotiation. If that fails, officers review the inmate’s medical and mental health records, consult with a psychologist or mental health professional, and assemble a trained use-of-force team wearing protective equipment.1Federal Bureau of Prisons. Program Statement 5566.07 – Use of Force, Application of Restraints, and Firearms The warden or a designee must approve the operation, and the entire process must be recorded on video from start to finish, including the identification of every participating employee.
Courts scrutinize planned incidents more closely than spontaneous ones, precisely because the officers had time to consider alternatives. There is no excuse for skipping safeguards when time allows.
What Officers Cannot Do
Force becomes illegal the instant it stops serving a security purpose. Striking an inmate as punishment for past behavior or perceived disrespect is retaliation, and it violates both policy and the Constitution. Hitting someone after they have stopped resisting or have already been placed in restraints is the same problem. Force must end the moment the threat is neutralized or the person complies. Continuing to use chemical agents or physical strikes on a non-resistant individual has no legitimate justification and exposes officers to both civil and criminal liability.
Excessive force is anything beyond what a reasonable officer would consider necessary under the same circumstances. Strapping someone into a restraint chair for hours to cause discomfort rather than prevent injury qualifies. So does using a high-level technique when a lower one would work. Chokeholds and deliberate strikes to the head, when other methods are available, frequently cause serious injury and lead to liability for the officer and the facility.
Pregnant Inmates
Federal law prohibits restraining a pregnant prisoner from the date a healthcare professional confirms the pregnancy through the end of postpartum recovery, defined as at least 12 weeks after delivery. Restraints are allowed only in two narrow situations: the prisoner poses an immediate and credible flight risk that cannot be prevented any other way, or she presents an immediate and serious threat of harm to herself or others. Even then, only the least restrictive restraints may be used, and several types are banned outright: ankle, leg, or waist restraints; hands restrained behind the back; four-point restraints; and being attached to another prisoner.2Office of the Law Revision Counsel. 18 USC 4322 – Use of Restraints on Prisoners During the Period of Pregnancy, Labor, and Postpartum Recovery Prohibited
A healthcare professional can order the restraints removed at any time, and the officer must comply. If restraints are used under one of the exceptions, the officer must file a written report within 30 days explaining the reasoning, the type and duration of restraints, and any observed physical effects. Prisoners must be told about these protections within 48 hours of their pregnancy being confirmed.2Office of the Law Revision Counsel. 18 USC 4322 – Use of Restraints on Prisoners During the Period of Pregnancy, Labor, and Postpartum Recovery Prohibited
Inmates with Disabilities
Title II of the Americans with Disabilities Act requires state and local correctional facilities to make reasonable modifications to their policies when dealing with incarcerated people who have disabilities, including mental health conditions. Department of Justice guidance says staff should try to determine whether disruptive behavior is related to a disability before resorting to force. When a prisoner with a mental health disability is acting out but doesn’t pose a significant safety threat, DOJ recommends calling in crisis intervention teams or mental health professionals, involving officers trained in de-escalation, or skipping discipline entirely and providing treatment when the behavior is clearly disability-related.3ADA.gov. Examples and Resources to Support Criminal Justice Entities in Compliance with Title II of the Americans with Disabilities Act Officials are prohibited from relying on stereotypes about a disability’s effects when assessing whether someone poses a danger. The assessment must be individualized.
The Duty to Intervene
Officers who witness excessive force have an affirmative obligation to stop it. Department of Justice policy states that officers “must recognize and act upon the affirmative duty to intervene to prevent or stop any officer from engaging in excessive force or any other use of force” that violates the Constitution, federal law, or department policy.4U.S. Department of Justice. Department of Justice Policy on Use of Force Standing by can expose a bystander officer to the same liability as the officer who used the force. Courts have held that failure to intervene is itself a constitutional violation when the officer had a reasonable opportunity to act.
How Courts Judge Whether Force Crossed the Line
The constitutional test depends on the status of the person who was forced.
Convicted Prisoners: Eighth Amendment
The Eighth Amendment bars “cruel and unusual punishments,” and that prohibition is the primary check on how correctional staff treat convicted inmates.5Cornell Law School Legal Information Institute. U.S. Constitution – Eighth Amendment In Whitley v. Albers (1986), the Supreme Court set the core test: did the officer use force in a good-faith effort to maintain or restore order, or was the force applied “maliciously and sadistically for the very purpose of causing harm”?6Justia. Whitley v. Albers, 475 U.S. 312 (1986) Courts weigh how much force was needed, how much was actually used, how serious the threat appeared at the time, what efforts the officer made to dial back the response, and how badly the inmate was injured. Under Hudson v. McMillian (1992), the prisoner does not need to show serious injury. Even a minor injury can establish a constitutional violation if the force was applied with malicious intent.7Justia. Hudson v. McMillian, 503 U.S. 1 (1992)
Pretrial Detainees: Fourteenth Amendment
People held in jail before trial have not been convicted, so they cannot be “punished” at all. Their protection comes from the Fourteenth Amendment’s Due Process Clause. In Kingsley v. Hendrickson (2015), the Supreme Court held that pretrial detainees need to show only that the force used against them was objectively unreasonable, without proving the officer acted with a subjective intent to harm. A court evaluates the situation from the perspective of a reasonable officer on the scene, accounting for the facility’s legitimate security needs.8Justia. Kingsley v. Hendrickson, 576 U.S. 389 (2015) A use-of-force incident that might survive an Eighth Amendment challenge can still violate the Fourteenth, because the objective-reasonableness bar is easier for a detainee to clear.
Documentation, Medical Review, and Video
Every use-of-force incident triggers mandatory written documentation. In the federal system, staff must prepare a Report of Incident covering every use of force, chemical agent, or restraint application, including situations where the inmate cooperated with being restrained. The report must identify every person involved, describe the incident in detail, and be submitted to the warden by the end of the shift.1Federal Bureau of Prisons. Program Statement 5566.07 – Use of Force, Application of Restraints, and Firearms Officers must articulate the specific threat or noncompliance that justified the force. Vague descriptions like “the inmate was being disruptive” do not meet the standard.
After any use of force or forcible application of restraints, the inmate must be examined by qualified health staff and any injuries immediately treated. Staff members who report injuries also receive an immediate medical assessment. These medical records become critical evidence, because they provide an independent physical record that can be compared against the officers’ written narratives.
Video matters just as much. Calculated incidents must be recorded from beginning to end, including identification of every participating employee and any decontamination procedures. For immediate incidents, staff must obtain a camera and begin recording as soon as feasible. Fixed wall cameras and body-worn cameras supplement these recordings. All video is preserved as part of the incident file.
After documentation is complete, the incident enters a formal review. Investigators compare written reports against video footage. Inconsistencies between what an officer wrote and what the camera shows are where cases unravel.
What an Incarcerated Person Can Do About Excessive Force
Someone who believes force was excessive has three overlapping avenues: the facility grievance process, a civil rights lawsuit, and a referral for criminal prosecution. The first is a precondition for the second.
File a Grievance Immediately
The Prison Litigation Reform Act bars any lawsuit about prison conditions until the prisoner has exhausted every available administrative remedy.9Office of the Law Revision Counsel. 42 USC 1997e – Suits by Prisoners That means filing a formal grievance and completing every step of the facility’s appeal process. Speaking to a guard, writing a letter to the warden, or filing an informal complaint does not count. Missing a single step will almost certainly get the lawsuit dismissed. Grievance filing deadlines vary, typically between 15 and 60 days after the incident. The clock starts running immediately.
Sue Under 42 U.S.C. § 1983
Section 1983 lets a person sue anyone who, acting under authority of state law, deprives them of a constitutional right.10Office of the Law Revision Counsel. 42 USC 1983 – Civil Action for Deprivation of Rights Two features of federal law make these cases hard to win.
The first is qualified immunity. Officers are shielded from personal liability unless their conduct violated “clearly established” law, meaning a prior case with sufficiently similar facts where the conduct was held unconstitutional. A general principle like “officers cannot use unreasonable force” is not enough; the precedent must define the right with a “high degree of specificity” so that every reasonable officer would have known the conduct was unlawful.11Supreme Court of the United States. Zorn v. Linton (2026) Unless the plaintiff can point to an existing decision with closely matching facts, the officer wins qualified immunity regardless of how the force looks on video.
The second is the PLRA’s injury rule. A prisoner cannot collect damages for mental or emotional injury without first showing a physical injury, unless the claim involves a sexual act.9Office of the Law Revision Counsel. 42 USC 1997e – Suits by Prisoners Even if the force was clearly unconstitutional, a prisoner who suffered psychological trauma but no physical harm may recover only nominal damages or injunctive relief.
Criminal Prosecution and DOJ Oversight
Serious cases can lead to federal criminal prosecution under 18 U.S.C. § 242, which makes it a crime for anyone acting under authority of law to willfully deprive a person of their constitutional rights. The penalties scale with the harm: up to one year in prison for a basic violation, up to ten years if the victim suffers bodily injury or the officer used a dangerous weapon, and up to life imprisonment if the victim dies.12Office of the Law Revision Counsel. 18 USC 242 – Deprivation of Rights Under Color of Law
When problems go beyond individual officers, the Department of Justice can investigate an entire facility. Under the Civil Rights of Institutionalized Persons Act, the Attorney General can bring a civil action when there is reasonable cause to believe that a facility is subjecting prisoners to “egregious or flagrant conditions” that deprive them of constitutional rights as part of a pattern or practice.13U.S. Department of Justice. Civil Rights of Institutionalized Persons These investigations can result in consent decrees that impose years of court-supervised reform.
Taken together, the qualified immunity hurdle and the PLRA’s injury rule make prison excessive-force cases genuinely difficult to win. That is exactly why early grievance filing and preservation of medical records, video, and witness names matter so much.
