Guns
The right to bear arms is NOT about blasting Bambi or shooting ducks, it's about a well regulated militia being necessary to the security of a free state.
In the 1930's machine guns became strictly controlled under the National Firearms Act requiring extensive background checks and a $200 tax for ownership.
To carry a concealed weapon in Virginia you have to visit the court house, file a form, get finger printed and pay $50 for processing and a background check. You also have to show that you have taken a gun safety course or have previous experience like being a member of the military.
Registering guns, smaller magazines and banning semi automatic rifles will do little in preventing crime BUT requiring citizens to complete a gun safety course and have a background check before they can can buy ammo might.
I wonder if we could piggy back on the current system of concealed weapon permits or come up with something that combined with an instantaneous background check could help prevent guns and ammo from getting into the hands of those who would illegally use them.
