I don't quite understand this part..."when he shows people how to use a gun to shoot a cop."

 

Do guns operate differently when shooting cops?

 

 

It beats me. Cops generally think they're the best thing since sliced (white) bread, but no, I'd suggest a gun operates the same regardless of the target. However, the environment may play a difference in the operation of a gun- such as not working underwater, or propelling the shooter backwards at an extreme rate if fired in outer space. : /

However, considering many police use flak jackets, I'd suggest a head shot is much cleaner if you're trying to kill a cop. Shooting them in the legs  or arms may also help to put them in "shock" for a later headshot. Simply put, unless you have armor piercing rounds, aiming for the heart is not a good idea if your goal is the death of a police officer.

This is clearly a First Amendment issue. It may have been stupid to say it, but it is our right as American citizens to say stupid things.
