They kind of do random checks. I have seen 85 year old white grandmas being searched. Thats just sad, I do hope they start profiling because even though I feel bad for the majority of Arabs that might not take their dislike of the US to the suicide bombing level, there are some who will. We have to prevent that minority from getting on the planes in the first place.
