What I think upset me the most is when I found out that the alleged shooter made posts and posted pictures on Twitter referencing what he was about to do, at some point last night. No one did anything about it. If one person would have spoken up and reported it, this could have all been avoided.
I know myself and the majority of my readers are very active in the social networking community and I think we all share a responsibility to report things like this. All I'm saying is, if you see something like this that might rub you the wrong way, it can't hurt to report it, whether they are a high school student or an adult.
RIP to the student that has passed away and I wish the rest of them a speedy recovery.
