As a LEO, never fire a warning shot - even in the performance of duty as a reason or excuse. As a private citizen, never fire a warning shot as you could very well be committing a criminal offense.
A guy tried to snatch a woman's purse at a Wal Mart in Texas. Several customers took it upon themselves to, um, deliver a little justice:
The lady in the white t-shirt fired a shot over the robber's head as he tried to get away. This is when he fell. She did not shoot him.
Was it the right thing to do in this situation? Are warning shots a viable tool? What would you have done had you been there?
Too much risk in a warning shot. It was against the rules we operated under during my LEO years for lots of good reasons. How would you like to explain your warning shot that hit an unintended thing or person in court?
Welcome from Florida, the warning shot capital of the world--legally.
I'm not satisfied it was a warning shot, I think she missed him or pulled the shot at the last second.
