Since when did a gun pull its own trigger? People kill people, not guns. In the UK, personal ownership of a firearm is verboten, yet people kill each other using sticks, hammers, chains, scissors, knives, and more. Do you want to get rid of cars too?
None of these things are designed to kill thirty people with thirty trigger pulls in thirty seconds or less. You go to a classroom, music concert, or business carrying one of those things and fifty people won’t die. Most will get away.
A gun's express purpose is to KILL. A car's express purpose is transportation. How come we all have to have license, insurance, etc. for car, but not for guns. Why do YOU think the US has hundreds of times more *school shootings* than any other country???
