Gun bans, drug bans etc.

Are just crap and false security for those who can't think with their own brains. Sure, people get shot and kill themselves with drugs, but so what? Tools and chemicals don't kill people it's always the people themselves who do that. When will we learn to accept natural fact of life that is death.

If we legalized drugs, I predict our murder rates would actually go down on average due to tougher prison sentencing due to greater availible space for prisoners in prisons, not to mention the end of violent turf wars and gang violence over drug disputes.
That's probably true. But will the effects on the populace of legalizing drugs offset these effects?

E.g.: people working while intoxicated, or learning nothing in university due to recreation. I'm not referring to individual responsibility here, but rather the collective influence on society.
