I concur with Springmom and others...Alibi Gun
..the fact that you posted this just deflated your chances of using it, and you will be in hot water if you do legitimately shoot someone who tries to rob you with a fake gun. What cops wouldn't check your computer if your involved in a suspicious shooting???
Anyway back to the original thread...you walk up on a guy who is robbing your car and he is not armed..can you blast him..No...but if he threatens your life or of your family...Yes. Life needs to be in danger. If you catch the guy robbing your car, you walk up on him, and he escapes, let him go and call 911. Shooting him in the back is manslaughter. If the guy is robbing your car , and you approach and he says "get in the car" or "Give me your money" and you feel you life is in danger, blast away.
