These shootings and every other related crime come down to one thing, RESPECT. Children are not taught to respect anyone, be it classmates, teachers, adults, or even their own parents. If they are taught anything, it is that they are the most important person in the world and that you shouldn't let anyone get in your way if there is something you want, and don't think about the person you backstabbed on the way up either or the person who's car you threw a rock at. I see it everyday, Kids make of people, harass them, or go out and vadalize property, etc. You know what the only thing that they think about even after they do it is, "How is this going to effect me?" Kids are not taught to think about how their actions will effect someone else's life. Basically, people just don't give a crap about anyone but themselves.
Looking at this shooting, on both sides of the spectrum, lack of respect caused this horrible tradgedy. First, the shooter was obviously not taught that you should respect other people and their right to live, very simple idea. On the otherhand, the people who made fun of him because he was different or whatever were not taught to respect other people's feelings, very simple idea as well. Now I'm not justifying anything that was done today by any means at all.
I'm just saying to parents, wake up and TEACH YOUR CHILDREN TO RESPECT OTHERS! I am so thankful that my parents taught me to care about others. Teaching your children a little respect will change alot. I'm also not saying that it was all the parents fault either, going to school right now I know that if I wasn't strong willed and had a good sense of right and wrong that I could have picked up some bad things, but then again I was brought up to be strong willed by my parents.
P.S. Sorry about any grammatical errors in this statement
