How stupid can it be? Ban all cars, so no-one will die in a traffic accident. Ban all matches and lighters, so that no-one will die in an arson. Anyone can buy a car for $100 and matches and lighters cost about 50 cents and are sometimes just lying around anywhere. Outagerous! How big fires can't one create with a box of matches?
Oh, and a Japanese kid actually managed to kill 7 other kids with only a knife. In Japan you can only buy firearms to collect them, but this tricky kid fooled the fantastic gun control and did it with a knife. So you must also ban knives.
And electricity...should we ban electricity or all things that a kid or an idiot could put in a socket? Wait, they usually put knives and chisels there, so we'll ban it all, of course.
All these steps will make everyday life incredibly harder; you'll not be able to transport yourself or chop your food or lit a fire or use any electrical device, but hey, no price is too high to pay when it comes to the nice, warm, fuzzy feeling of security...
