Criminals are not going to make any type of firearm. They either going to buy them illegally or steal them which is still illegal last I knew. People that would use this information are not criminals and by very definition pose no threat to society. When are people going to learn this is not about guns or crime, this is about control. Our government is corrupt and more powerful than it should be. Power currupts and absolute power currupts absolutely. The government wants absolute power nothing less.
