Why do police put themselves and the community they have sworn to protect in jeopardy trying to capture a cornered criminal through force?

Protect or evacuate neighbors.

Turn off all utilities.

Wait.

Arrest perk when he exits.

Loss of life or injury to police and civilians has been minimized.

Why does every encounter need to end like a Wild West B movie?
