Any one who would say such a thing has already proven themselves to stupid for words.
Wasn't it Samson who in the Bible killed 300 men with the Jaw bone of a donkey.
Sensible people understand that if determination is there the weapon is not important.
Ulmas done good to rub this morons nose in their stupidity.
I believe it was 1,000 men. Let's just consider the other ways these evil people could inflict harm on society like the bombing of a school here in the US back in the 20's, the Chechnian rebels taking over a school 8-9 years ago and planting explosives, chemical/biological attacks, flying airplanes into buildings, arson, running into crowds with vehicles, turning children against their parents, propagandizing a populace against a minority...
So when was the last time some one proposed controls on who can buy a lighter, a car, or a news outlet? Evil lurks among us and the only way to deal with when it rears is ugly head is quickly and violently which means we always need to be vigilante and prepared.
