George Zimmerman was charged last week with the second degree murder of Florida teenager Trayvon Martin. Prosecutors claim that Zimmerman “profiled” Martin, assuming he was a criminal based on his appearance. They have not explicitly accused Zimmerman of racial prejudice, but Martin was black and many are asking the question. Such profiling would be illegal for a police officer. But rights groups say it often happens. They worry it will become even more common thanks to Arizona’s new immigration law, which is the subject of a Supreme Court hearing next week. Join Diane for an examination of profiling, and its impact.
