But they do have higher rape, violence, machete deaths, stabbings, etc. Guns sometimes kill innocent people, but they can also kill bad people and save good and innocent people. No other instrument can protect, equalize the gap, between a 100 pound woman and 6'5 man (aka avg sherdogger) like a gun. It aint a black and white subject, but America's forefathers saw it fit to put them so high on the priority list that they placed the right to bear as the second amendment. And if you ban guns, the only people that are going to still have them are the criminals (banning drugs/rape/murder did not stop criminals from doing them) and big brother/tyrants (the whole reason the forefathers wanted the citizens to have guns in the first place).
Im willing to bet that if Cain really just wanted to hurt/kill someone, he would not need the gun. It's easy to heap this on a scapegoat like a gun, but there is alot more here, and we dont even know what happened yet.....heck, maybe without the gun Cain is dead now.
