San Francisco crime problem runs deeper than rosy statistics from city, expert says

San Francisco's crime statistics appear to compare favorably to other major U.S. cities on the surface, but one expert argues they don't paint the full picture.

"People do not report these crimes because when you have a DA who's pro criminal and not going to enforce the law, the cops aren't going to go out and arrest somebody when they know the case is going to be no papered."

Stimson's comments come in the aftermath of the killing of tech executive Bob Lee, who was fatally stabbed in an area of San Francisco typically thought to be one of the city's safest and most upscale.
