I was in Iraq & even in an actual theater of war,unless you were immediately fired on we had several steps to go through before kill shots. we had rules of engagement and escalation of force cards my command made us carry on us at all times with those regulations. even when a car possibly carrying explosives was barreling down on us, we were taught to exhaust several steps of warnings before killing: hand signals, flags, pop smoke/flares, warning shots to the sides, disabling shots THEN kill shots. so for the life of me, I can’t figured out why on the streets in the United States of America, police officers go immediately to murder and people are just like “well, in the heat of the moment…”
