San Francisco officials are taking tougher measures to prevent potential fan violence on Super Bowl Sunday when the 49ers battle the Baltimore Ravens in New Orleans. More than 400 officers will be on duty, triple the number on a normal Sunday in San Fran.

-- If you think this sounds like overkill, please watch the Real Sports segment on Fan Violence. Candlestick Park is one of the most dangerous Stadiums in the NFL and 49er fans are among the most violent. Thank god they aren't playing the Raiders in the Superbowl.
