I realize that this is an emotional time, but I think people yelling at each other with emotional and anecdotal arguments need to calm down before they start screaming their opinions on American gun laws. I can recommend some excellent books to form an informative opinion on the subject. I will say this, my personal opinion on guns is that they are tools. I think the problem is the glorification of violence in American culture. As we've seen, outlawing particular things usually backfires. Now that's not saying I'm completely against gun control. I think you should at least go through some psychological evaluation before you're allowed with a weapon OF ANY KIND. You can easily tell that knife crimes increased in Britain after their extreme form of gun control. Point Blank: Guns and Violence in America by Gary Kleck As far as Americans and their guns, Lien, open carry is very-very rare and only acceptable in certain parts of the US. If you actually want to carry a weapon, you have to have what is called a Concealed Carry Permit. Which is actually pretty hard to obtain despite media bias. I hope this post in informative, this is an extremely tragic event and I personally think it's too soon to start casting blame on anything other than the person who committed the crime. Emotionally charged arguments usually backfire. It would be better for us all to spend this time mourning and then collectively come up with a solution.
