Out of over 1/4 million people involved, one is a nut-case that actually acts out. Considering the stress of the situation, I do not find it terribly unusual that one would crack. This is likely someone would have cracked at some point, no matter what their situation (i.e. in the military or not).
There is also no solid info on whether his being Muslim was a factor either. There is a great deal of misinformation and speculation being reported all over. The only report I give any weight is the Sky News report, since that reporter is at the scene.

Right. Purely cooincidence. Like the 15 911 highjackers, the Egyptian at the El Al counter in LA, The DC snipers, Sammy Al Arian. Complete cooincidence. How deep in the sand is your head buried?

Yes, I am sure it was simply a coincidence. Like Mohammed and Malvo the snipers, or Mohammed Atta and his 18 buddies, etc etc etc.

I'm sure it's all just a big coincidence.

Nothing to see here folks, move along.
