"Muslim communtiies have been cooperating with the FBI"
That's funny. I've read many article on FR since 9-11 describing how Muslims have been instructed by their Muslim organizations, and, IIRC, the ACLU and its ilk, that they DON'T have to cooperate with the FBI.
So your blanket statement is very, very odd.
Just saying what the FBI is saying
Also please dont fall for this thing that all Muslims listens to these groups. Most muslims dont care and they are too busy getting on with their lives and frankly dont care.
