What I can't help but think is why would anyone want to do that job?
1) Good pay
2) Never ever ever get tickets
3) Get to hurt people and no consequences
4) Get viewed as heroes
5) People HAVE to do everything you say or you get to do #3 (fun fun!)
6) Even when lying, your testimony is cherished by the courts and juries
7) Retire super early with fat pension
8) Sweet tacticool gear like thigh gun holsters and camo gear to make swat teams invisible in urban environments
9) Badge bunnies
10) POWER
Why would you consistently expose yourself to situations where the best possible outcome is nobody dies, and the worst possible outcome (if you make the wrong decision, as this guy clearly did) is something beyond an entire nation wanting to see you hang.
You call that a "wrong decision"? The intentional murder of someone running away from you is a "wrong decision"? Maybe it's just me, but I think it's a little more heavy than that.
nobody you interact with on a daily basis being happy to see you.
When the majority of your interaction with people is forced on them against their will under threat of deadly force, and the interaction will likely cause them to lose money or freedom, why would you expect them to be happy to see you? This post reads more as cop masturbatory material than a genuine reflection on why a cop would choose to be a cop.
