Many young (and not-so-young) men, black or brown, know what it's like to be stopped by a police officer for doing, well … nothing. It's called DWB — Driving While Black.

And it doesn't stop at being stopped. According to a recent study from the Justice Department, African-Americans and Hispanics reported that police used force or threatened to use force against them twice as often as whites said they did. After years of denying racial profiling, law enforcement officials all the way up to U.S. Attorney General John Ashcroft are conceding there may be a problem and that it must be fixed.
