Yes, I understand that most, perhaps very nearly all muslims don't want anything to do with these nut-jobs. However, if you're looking for the group of people most likely to be in to this kind of thing _right now_, then it seems that the nearest crazy-horse mosque might be the place to go. No, not the mosque around the corner from you right now [for most values of 'you'], but such places exist, and its right for law enforcement to investigate them.
Don't misunderstand me. Killing civilians with secret orders via remotely piloted drones, with no trial, no public investigation and no accountability is broken. Obama has certainly given me hope. Just as Bush did before him. I _hope_ that the next holder of office is a little more responsible.
But, there is a war. And I'd rather the liberal democracies won it. [hint - if the nut-jobs who attached the shopping mall in Nairobi had their way, my children and I would be executed in a flash]
Check out what's going on in Burma, Thailand and the Philippines.
Step back and look at events around the world, you'll see a clear pattern.
Narrow and blind hatred from other people lets them continue doing it. The number of people killed under the guard of the "new" Burma far exceeds the toll in Nairobi and Nigeria.
