Yes, ban guns, ban knives, and ban anything that could possibly be used as a weapon.
And before you conservatards flip out and post some stupid comment like, "durrr how culd we inforce dat ur dum lol", Australia already has exactly this policy in place. Hammers are considered tightly-regulated weapons of mass destruction there because they, too, can be used as weapons.
It's time for America to step into the 21st Century and outlaw all weapons, as well as anything else that kills people.
right---ban cars.
Ban humans, humans kill, we need to end this madness.
Ban lions, tigers, whales, bears, rats, wolverines, and alligators, because they all kill other living things to survive.
Ban all elephants, cows, giraffes, buffalos, zebras, horses, rabbits and sheep, because they kill other living things, the only ones worth keeping, you know, the plants and trees etc. that purify the world from the evil carbon dioxide that the aforementioned monsters exhale.
