Humans have been killing each other as long as history can remember. The tools have just changed. Even if guns are banned, they will still get into the US and still be used to kill people. And even if real guns are outlawed, there are plenty of way to make deadly firearms out of things you can buy at WalMart. Hell, recently there was a guy who made deadly weapons with just what he bought in the airport gift shop. I think that everyone should have some sort of way to defend themselves in their house, preferably a shotgun. I don't understand why people would need assault rifles, and I definitely dont understand the open carrying of assault rifles. Smart guns are becoming more popular and I hope to see more of those. But seeing as members of the NRA sent death threats to people who carry them, I doubt they'll get very far.
