But where do you draw the line with "people that look a certain way?" Do you think we should profile all Muslims because of how a group of crazy people who call themselves Muslim act? Or that we should profile all normal looking middle aged white men because they're most likely to be serial killers? Or all inner city black kids because of how they dress (if they dressed "white" they would get their asses kicked). And "working hard in their communities toward changing the behaviors that led to the prejudice in the first place" is not such an easy thing to do when education is what will pull a community out of the gutter and no funding goes to the inner city schools. Profiling works in the same way that trawling for fish with a giant net works. And when you group the good people in with the bad just because they look similar, you will never win that communities favor.
