That's true ....but it can also show how it brought people from all over the world together .....the outpouring of outrage and compassion for the victims is powerful.
 
if a psycopath is going to kill people I think serial killers like Bundy, Ramirez, Gacey and such would be what they strive for....these school shooters are cowards (as are ALL killers - don't get me wrong) but the school shooters are using the most lame reasons to kill - whereas the real serial killers actually have forces that drive them to kill over and over....I honestly believe they are mentally ill - where the school shooters are perfectly sane... and the killings are acts of revenge over real or imagined wrongs done to them. 
I do feel sorry for his family - that boy just plain had evil in his heart 

 but just taking a gun and shooting innocent people is the act of a true coward
