Sure, that's the same thing as a one time incident....
Average of eight kids shot by unsecured firearms daily...
Tons (like 40 per two weeks, reported) gun fails where idiots that don't have gun "control" shoot themselves and others by accident, and then you have the cyclic mass shootings.
So which of the "gun control laws" do you feel was enacted in one isolated incident, and what effect? It's not as if it is hard for either a responsible gun owner OR a moron that doesn't even have basic safety consciousness to buy a gun.
It would be like advocating everyone has a right (with no hinder, no exceptions) to buy and fly an airplane. No need to take lessons, prove you can fly, pass a test. Just any Clem that wants to can go out and fly.
Making laws after one incident is a bad thing in general. Gun incidents are daily occurrences.
