Go look it up.....
No actually, I'm not talking directly genius. I'm speaking from a metaphysical type secondary effects position. Such as, the ready availabilty of guns to the population make it easier for those who would use them for ill-formed purposes to have them rather than having stringent safeguards which would make them at least have to pay through the nose for them. It makes it harder for retards to have them which wouldn't keep them from their kids getting them or at least teaching them how to use them. I'm not saying that everyone who has a gun goes out and shoots people.
