Where is the love?

I'm writing this post in honor of the 27 people who died in the Newtown shooting.
Today, during my fourth period class, you could tell somethong went wrong. My alegebra teacher came into the room, obviously distraught,and called my teacher over. My English teacher began to cry, though she was hoping we wouldnt notice, and proceded to close all the blinds and check her phone. I was one of the firt to hear of the shooting from a friend who overheard the teachers, and sat thr through lunch, panicking with one of mmy frieds,who like me, gets easily paranoid. The bell to signal the end of lunch, we were just chaperoned out silently, told to go silently straight to our next class,which for me was art. I sat in the room, shaking and trying not to cry, and most people didnt even know why we wer in lockdown.  My friend and I signed back in fourth, a brief exchange, but we didnt   we couldnt tak about it.
"U ok?"
  "No. I know."
*Nods*
  "My fream."
I was so shaken up, not just because of the evwnt, but only two nights before, the dy of the Oregon mall shooting, which is most likely wht cused the nightmare, I had this awfawful  dream that my achool wenr into total lockdown, where we were all to co to the cafateriacafeteria  at once because  shooter was approching the school. It was the worst dream I for awhile, and this real lockdown  felt too real, like the  and was on extreme paranoia until I hard the shooters were cught/killed.

Why is there such cruecruel ,  evil people in this world, who one day decided to go shoot childrennchildren ? Why?
