How much money should it take for a cop to be able to open fire on a suspect?
Broadly speaking, the police shouldn’t be using lethal force unless someone’s life is at risk.
But that gets us to the “we think he might have had a knife” excuse, which is just taken at face value as Carte Blanche to do as thou wilt.
The escalation of force from “jump a turnstile” to “four police trying to surround and tase the suspect” is more tied back to the $2.90 cost. Had they simply shouted after the guy as he fled, nobody would be in the hospital right now. Instead, they went Commando Mode, and bystanders paid the price.
