thats the chris rock method.. he invented it
good idea in theory but the ingredients of gunpowder arent hard to come by. people would just have bootleg bullets.
and yes people will always kill each other , even if it was with a spork.
Guns offer a unique way to killmany people quickly.. with a knife or rock , your not going to be killing 32 people so quickly..
so i think there is still room for some gun control.. in canada you have to take a course and exam before you get to own a gun , and even then you cant just carry it with you, you can only take it to the gun range..
i think those three steps would limit alot of whacknuts from getting guns..
