Where Are We Safe?..........

Ok, so what is this world coming to? You can't even go to school for a degree in anything without looking over your shoulder trying to figure out if someone is going to flip. I didn't take Columbine as hard as I could have but was happy that I had graduated the year before. Now this, the largest massacre of its kind ever in History. When do we start reading into things more then usual as a teacher so that stuff like this doesn't happen? When do we start to seek help if something like this comes up?
