I think there should be basic regulation.  I am not against people owning guns.  After all around 50% of gun deaths are suicides.  But I do think basic requirements should be met such as not being crazy.  I also feel that people should show proof of insurance just as when they buy a car.  You have to do this when buying a car, why not a gun?  Also when someone buys a lot of gun, he should be mentally evaluated every 3 months.
