You of the gun culture have never provided any of us any new or old reasonable restrictions on having or obtaining guns or any limits on their capacity.
I haven't seen anyone give us reasons why we can't have poison gas, tanks, howitzers, and handy back-pack nuclear explosives.
Maybe mount cannons on our yachts.
Are those all OK. Shall not be infringed?
The very fact that you state what does exist in prevention shows your ignorance, mallcontent!
Why we can't have P Gas, tanks, howitzers, and nuc back-packs explosives is already established. They are already prevented. The fact you ask is proof of your frickin ignorance! Moron!
