The bolded part will get you put in prison for murder, or if you're a ****ty shot, attempted murder.
No matter how much you despise a thief, you CANNOT SHOOT TO DEFEND PROPERTY. No matter what state you are in, this is NOT NEGOTIABLE AND YOU WILL GO TO PRISON FOR THE REST OF YOUR LIFE IF YOU DO.
In Louisiana, and a few other states, they are "right to confront" states. Meaning.....and carefully read this, you may "confront" someone on your property with a gun. And you do NOT have to back down. If they are willing to charge at you, or reach and possibly pull a gun of their own out even staring down the barrel of yours, then you can, and ONLY THEN, have the right to shoot to stop the threat. Notice I didn't say "shoot to kill." If you shoot them in the back, for instance, you'll go to prison. No one is a threat to you running away. I had a concealed handgun permit and took and passed the required course without problems. I learned a lot. CC permits are about when NOT to use a gun, not when TO use one. Basically, if there is ANY doubt whether your life is in danger, it's probably not and it's your adrenaline pumping. Keep the gun squarely on his chest, give him a chance to leave, and call the police. Let them do their job. Yours is only to survive.
Not long ago someone broke into my truck and stole, of all things, my radar detector. I was prepared, and still am, to confront him with lethal force, but ONLY if he comes after me and you MUST give him an "out." You can't corner him in a fenced yard and then tell him if he comes at you he's dead. You're giving him no choice. He must be given a way out. He does NOT have to stay when you say you will hold him at gunpoint until the cops arrive. If you shoot him when he is trying to get away, you will spend the rest of your adult life in prison.
You MUST be careful with this. If you want to go to prison for life because someone is stealing a purse, that is your personal choice, but I believe it would be one you would regret the day they slapped the handcuffs on you. You can always buy another purse, you can't take back a poor choice like lethal force.
