One of these "fans" could be a cop on Sunday

The 49ers and the NFL have adopted extraordinary security measures for Sunday’s NFC championship against the Giants after Saints fans complained of harassment by unruly 49ers faithful last week according to the Associated Press.

Undercover police will be dressed in Giants’ garb and on the lookout for nasty fans. Giants ticketholders will be handed a card as they enter Candlestick Park with details on how to contact police if they feel threatened. And more security cameras and undercover police officers will be in place to identify abusive fans.
