All Al-Qaeda and similar organizations are full of muslims. With some exceptions, all the terrorists (atleast the ones against US) are muslims. 9/11 was executed by muslims. What is the new information in all these? How does it justify searching a vast majority of muslims who are peaceful? If you have specific information (as with the latest case of conspiracy), search them, arrest them, punish them, whatever. And moreover the latest bunch of people arrested were American citizens, their religion notwithstanding. If it turns out(I am convinced that is the case, still) that the number of 'islamic american citizens' involved in any type of terrorism is ridiculously small, then you are going back to the cavemen era, by implementing arbitrary laws based on racial prejudices. I agree with LLC, the logic is totally retarded.
