Those people who "don't care" (about our Constitution, and the freedoms associated with it, which includes the freedom of religion) and literally treat someone poorly are themselves a problem to any success in defeating radical Islam
That said, I do fully support profiling. Not to the point of treating someone unfairly, simply I would keep a more investigative eye on someone who's a young/middle aged looking male, with a complexsion consistent with other Arabs. I don't care if that's not "politically correct", since its PC that is largely destroying this country. Same holds true, if I see some suspicious looking fella in a hoody, with low hanging pants, & multiple tattoos, in that I'm going to keep a closer eye on them, than Grandma Frisby, in her power scooter.
Did you read the story about the neighbor to these 2 San Bernadino killers, who saw what they believed to be suspicious behavior, but chose to keep it to themselves for fear of being branded a racist?? I can't imagine how bad they must feel, in believing that had they spoken up, 14 innocent people would have been saved from being murdered
