I never understood what point is to go randomly shooting **random** people. Especially kids. Why not lawyers or bankers or IRS workers or politicians? Because
1) you will get caught, and most likely shot
2) media attention drains quickly, it won't be news after week or two
3) It doesn't change anything*
4) You wasted bullets pointlessly, and your life, and uncountable other material and moral resources
* Sure, for the close ones of the victim, and of course, victims themselves, but hurting 1-20 people among 6 billion is not something that makes world spin other way nor solve problems
If I was sick, desperate, disoriented and crazy maniac and angry at power, I would act stealthily and commit big things. Like poisoning entire city water supply or something. Bring true terror. And never get caught. Maybe give a tip to the emergency so they'd resolve problem before anyone gets hurt, but still make everybody afraid and power figures appear weak and helpless. Actually, it shouldn't be poison, but a truck full of laxatives...
But then again, supervillains are getting out of fashion with that boring and pointless hunt for Ol' Osama.
This guy clearly has a screw loose. And it doesn't really sound like there's any religion behind this.
It's simple mental disorder.
Also, I agree that labels are bad. Communities? Churches? Gays? Unitarians? Christians? Linux users?
I see making a church, closing doors and singing there, preaching yourself "different" and asking others to join as an act of extreme isolation. This is first reason why I'm practical atheist. I don't want to be a part of the flock, because I am not a sheep, damnit. If I believe, I don't need separate house, a book and a fool in black clothes to confirm this and continuously rate how "good"(like it could be measured) "believer"(like it had exact definition) I am.
Aren't we, ehm, human beings? Isn't that "label" more important than other ones?
