Although you find it interesting I find a few things about it disturbing in your views of Middle Eastern people.

You assume the agencies are watching all people of Middle Eastern descent...this may or may not be true but to heighten the paranoia of these people is a bit to me likened to racism.

You point to them that people are getting their heads chopped off and they were unaware, this heightens their fear again in that their father/brother or whatever could be killed for being an American at this point and viewed in a different light.

You take their comment of making bombs which was probably an off the cuff comment at that and turn it into a very serious threat to their personal security and safety.

Government sanctioned racism...this is its results
