"it isn't assult when its defense"....tell that to George Zimmerman. He was just defending his turf eh???
Canna m8, the use of deadly force, under any circumstances outside of those whom are permitted to use deadly force, is a federal offense. Its not a commonly prosecuted offense, but its still a federal offense. Its a grey area smole. Other than that I completely agree with your post
Its extremely hard to prove in a court that you knew your life was in grave danger...even harder to get someone to agree with you especially if they weren't there at the scene.
More often than not, if you are involved in a act that you resorted to using deadly firearm force to protect yourself, you can forget about keeping those rights
Thats not a message the Government will allow to be spread. Sure its okay to blast Johnny-O if he sneeks in at night for a TV, or TV Dinner for that matter.
Mind you though, that some states, have state level laws that directly conflict with federal law. IE....Florida's stand your ground law. Federally its illegal, but nobody is making a stank about it. Same deal can be said about the states that just "legalized" cannabis on a state level.
