As much as I'd like to believe things like this will begin occurring less and less, I have little faith that they will. I think we are still trending in the direction of society succumbing to more and more violence.
I do agree that we are becoming less and less safe in our lives. I grew up in Baltimore and was robbed at knife point when I was 18. Maybe that just makes me more aware of the violent people I may share my community with. If anyone really thinks that these mall shooters are rare individuals, they are completely wrong.
