Racial Profiling.... good or bad?

Do you know why law enforcement uses it? Because it works. When looking for a serial killer, they look at white males. Why? Because in the past, most serial killers have been white males. Everyone is fine with that! That’s cool! But when looking for terrorists… they look at people of middle eastern descent. Why? Because in the past, many terrorists have been of middle eastern descent. Now, this all of a sudden statistics becomes racism? I don’t believe we are giving any liberties up to buy a little temporary safety. What are your thoughts?
