Your conclusion is a straw man.it is a false dichotomy, but it is exactly what Derec and LP and coloradoatheist appear to be arguing.
No, what we are saying is that you guys are expecting a totally unreasonable standard. You want the cops to basically die rather than shoot.
Still waiting how our soldiers can be expected to refrain from blowing any unarmed civilians in a war zone unless they clearly have a weapon, but police officers cannot
Soldiers aren't trying to arrest people. Thus they aren't likely to encounter the sorts of situations that cause shooting errors. They also have less direct contact with the people around.
