This scenario struck me as I was driving home today.
Let's say you become involved in a use of deadly force confrontation in the parking lot of a chain restaurant. It could be a carjacking, or an attempted armed robbery, or a violent physical assault. Take your pick. The fact is it's you, armed, against one other person, also armed.
The restaurant is located at a busy intersection. You are behind some cover, i.e. a large mailbox or a telephone pole. You are being fired upon. The assailant may be coming towards you. He is in such a position that if you shoot and miss, your bullet could travel across a heavily travelled road, or into the restaurant. If you step out from behind your cover, you have a cement wall as a backstop.
What do you do?
