It has been proven that restriction on lawful ownership increases crime.

The FBI proved it, there is a big write up by two scholars that proved it by an exhastive research study.
All the articles are on the NRA wbsites.

Look at Great Britain, heck, not only did violent armed crime increase due to restrictions, but the poor saps who protect their home and property are considered the criminals when they harm the bad guys and do long jail sentences while the criminals go home with a slap on the wrist.
No freaking joke.

Look the district of columbia with the highest crime rate in the nation.
The good guys are disarmed and the bad guys have free reign.

You watch how quickly that crap stops if the CCW laws ever get passed.

Go look the articles up on the NRA websites, they are very informative and written by some pretty smart guys. I don't have the time to feed you the articles myself, but you naysayers always want proof, but when presented with it, you still deny it.
