I do understand the profiling aspect, as I studied that in my criminal investigations class in college. However, I also feel that there's that fine line between profiling, and racism, that seems to be crossed more often than not.
How could you possibly tell the difference? Unless a cop or such enforcement blatantly referred to their person of interest with a derogatory word, they could profile any race/homosexual/non-christian/etc. the same way...I really don't understand how you could tell the difference.
