Right, regular citizens are not afforded the same kind of leeway that police have when they shoot people. You might be alright with that, but I certainly am not.
There are sound specific reasons for it.
Here in the state of Washington, the people have less stringent standard for justifiable homicide than the police. At least on paper. And has been ruled as such in several cases over the last few years. (Guy shot in the back stealing a truck, kid shot in the back after breaking in and running away with some belt buckles, guy shot in the back as he was trying to knock down a door into the house (dad was outside, mom and daughter inside).
