A. you are assuming that powdered metal rounds were used, and B. whether buckshot is coming through the door or pieces of a lock is 99% irrelevant to the legal statute as far as when you get to shoot cops.
When someone starts shooting at you, are you supposed to make sure they’re not blanks before returning fire?
I have to agree with Fargo here. The people inside the house have no way of determining what kind of rounds are being fired at their door.
This kind of action led to the Barnes decision a few years ago, which led to the General Assembly's "yes, you can shoot a public servant (in some situations)" use of force statute. I have been concerned since then that some "less sophisticated" individuals will use force against the police when they are NOT legally justified, relying on their Donnie Baker understanding of the law.
