Gun Control and Safety

I think the shooting at Sandy Hook Elementary in Connecticut, was very tragic and shocking to our country. In my opinion, I think 20 year old, Adam Lanza, was insane to kill those innocent children and teachers. Also, shouldn't the school have had some type of security on their campus? Adam Lanza shouldn't have gotten in that easy. In Connecticut, it isn't that hard to get your hands on firearms. I think the laws should be stricter so that something like this does not occur again.
