Use of Force, De-escalation, Crisis Intervention, and Officer Wellness
The force standard
Graham v. Connor governs: force is judged by objective reasonableness under the totality of the circumstances, including the severity of the crime, the immediate threat, and whether the suspect is actively resisting or attempting to escape. Tennessee v. Garner limits deadly force against a fleeing suspect who poses no significant threat and requires a warning where feasible. Texas law permits force in limited circumstances, but agency policy may be stricter.
De-escalation uses time, distance, cover, communication, and reduced intensity when feasible. It is not a requirement to disengage or to avoid force when force is necessary. Officers must intervene to stop excessive force and render aid. Crisis intervention requires recognizing mental illness, intellectual and developmental disabilities, autism, deaf or hard-of-hearing persons, and hyperactive delirium. A peace officer emergency detention under Texas health law requires probable cause of mental illness and a substantial risk of serious harm.
Officer wellness
Understand cumulative stress, critical incidents, PTSD, suicide risk, substance abuse, sleep deprivation, peer support, and fitness. Seeking help is a strength and should not be treated as weakness.
Traps
"Least amount of force" and "proportionality" are policy concepts, not the constitutional test. De-escalation does not always mean disengagement. A warning before deadly force is required only when feasible. Deadly force is not a general property-protection tool; Texas property-defense provisions are narrow.
Worked example
A knife-wielding subject advances. Apply Graham: severity, immediate threat, resistance/escape. Rule of thumb: would a reasonable officer, knowing what the officer knew, believe the force was necessary?
