not really sure. depending upon the state and a few other factors, any individual can get his hands on a gun, legally, within a matter of days. and, even in some of the situations where the gun needs to be registered, not much is done to get the person using the gun registerred.
personally, i think if guns were put on a par with cars, there'd be a lot less "casual" guns out there, ensuring that people who dont need them wont get them.
