I am not insane, I am angry.  I am a cross dresser.  I killed because people like me are mistreated every day.  I did this to show society, push us and we will push back. … All throughout my life, I was ridiculed, always beaten, always hated.  Can you, society, truly blame me for what I do?  Yes, you will. … It was not a cry for attention, it was not a cry for help.  It was a scream in sheer agony saying that if you can’t pry your eyes open, if I can’t do it through pacifism, if I can’t show you through the displaying of intelligence, then I will do it with a bullet.

The parallels to Newton are spooky:  Smart kid starts the day by killing his mother and then going to a school to kill as many as he can.

At Pearl High School however Luke Woodham was stopped by the school’s principal who ran out to his truck a retrieved his .45 handgun.

The Wiki article is short.  Worth reading.  Newton could have been very very different if someone in or very near that school was armed.
