Actually, I think MOST of us support common sense measures to end gun violence. However, these measures DO NOT need to be any more laws. They need to be enforcement of those that are on the books - even when it applies to government agencies, and a serious look at our society as a whole, and what we can do to fix the mental health issues that lead to mass killings.
I don't tweet! I don't do face book! In fact the only thing I use my smart phone for is phone calls. Why did I get a smart phone? Because my wife told me it was a necessity! It is! I use it to hold down papers on my desk!
