Jim Sanders has the story in the Sacramento Bee.
Teams already revoke season tickets from problem fans. The situation at Candlestick Park over the summer presented special challenges. Bringing 49ers and Raiders fans together invites volatility. The game was played at night, adding another dynamic. Also, more fans sell or give away their tickets to exhibition games, lowering the bar for entry.
The 49ers ramped up security for games last season. The team announced a plan to have police officers wear New York Giants jerseys for the NFC Championship Game after New Orleans Saints fans reported taking abuse during the divisional round.
It's not clear whether the 49ers would support the new legislation. They've made technology a top priority for their new stadium. Some of that technology could presumably help on the security front.
"Offenders' names and photos would be published on the Internet and sent to sports arenas, police agencies and ticket vendors by the attorney general's office, which would maintain the list," Sanders wrote. "Sure, banned fans could sidestep the law and have relatives or friends buy tickets for them, but if they subsequently caused a commotion and were discovered at a stadium, their presence could draw a one-year jail sentence and a $10,000 fine."
