The Dude

You don't have a clue as to what you are talking about. People this is why you can never take to heart anything you read on forums like these concerning gun laws. It is your responsibility to know the law and you need to get it from a reputable site, not just what some dude heard.

The"stand your ground law" likely doesn't apply here. Will was inside of his own car which is an extension of your home in Louisiana. The fact that Hayes approached Smith while he was in his car and then turned around to go get his gun throws out stand your ground.

There are other scenarios where it could be ruled as self defense but most judges would throw out the Stand your ground argument in this case.
