Seems to me the right to bear arms are already being infringed on as bearing arms means to carry around with you. The way the laws are now it is a privaledge not a right to bear arms such as pistols and try to carry a shotgun down a street in New York!
Here we get into the living constitution thing. Some think that it ought to be the same as 1700's, in that case the only arms they had was muzzle loaders and single shots. Therefore that is it, no automatics or revolvers and such.
My viewpoint is that a person should be able to posess and carry handguns, rifles and shotguns. Automatic weapons, grenades, missiles and other war items are not neccassary and the 2nd does not state the reason for an individual's right as it does for the militia.
