Lesson: Police as Default Mental-Health First Responders

What is it?

This lesson captures a recurring finding: when police are the default first responders to mental- health crises, encounters more often end in arrest, injury, or death than in connection to care. It motivates the shift toward health-led crisis systems.

Why does it matter?

Officers are trained primarily for law enforcement, not clinical de-escalation, and a badge and weapon can escalate a crisis. People with untreated serious mental illness are substantially overrepresented among those killed in police encounters, an outcome crisis reform aims to prevent.

How does it work?

Absent a 988-linked crisis line and mobile teams, 911 routes distress calls to police, who must choose among arrest, hospital transport, or leaving the scene. Crisis Intervention Team (CIT) training helps but does not substitute for a health-led response with somewhere to refer people.

Who benefits?

Learning this lesson benefits people in crisis and their families, and police departments themselves, which are relieved of clinical roles they are not equipped for when alternatives exist.

Who may be disadvantaged?

Where the lesson is ignored, people with mental illness — especially those who are Black, unhoused, or rural with no other responder — face the greatest risk of criminalization or harm.

What evidence exists?

NAMI and multiple analyses document that a large share of people killed by police had mental-health conditions, and that CIT alone shows mixed outcomes without a broader crisis continuum. SAMHSA’s guidelines therefore center non-police mobile crisis response.

What tradeoffs exist?

Removing police entirely raises legitimate safety questions for a minority of dangerous situations; the evidence favors a tiered system where health responders lead and law enforcement assists only when genuine safety risk requires it.

Common misconceptions

A misconception is that most crisis calls involve violence; the majority do not. Another is that CIT training resolves the problem — it improves encounters but cannot replace a place to send people or a clinician to respond.
