Most people don't realize that it's legal to own a machine gun but you have to get a special license and you have to disclose all the guns in your house to the police. This is for the safety of law enforcement in case your house ever gets broken into.
The right to bear arms is no longer a matter of right or not. Now a days there is too much people with mental problems that have guns. Im a true believer that for you to have the right the bear arms you need to go thru a mental evaluation and then continue to have one as long as you still have your weapon.
