Starting next week, law enforcement officers policing the Bay Area Rapid Transit (BART) system in San Francisco, Sacramento, Oakland and other cities can issue bus and subway bans for unruly passengers — and according to one local news report, that power could be used to prevent political protesters from getting to demonstrations or essentially going anywhere.

Under the recently passed State Assembly Bill 716, BART can issue “prohibition” orders to any passenger cited or arrested for certain offenses, essentially blacklisting some people from boarding public transit vehicles if they’ve been charged with certain crimes.

BART Board President Tom Radulovich told Bay City News the law is “an important safety initiative to keep our employees and riders safe,” adding, “We’re very concerned that for the past few years folks have been assaulting our station agents.”

"We are really wanting to send the message that if you are going to come onto our system and be unruly or violent, there are going to be consequences,” BART spokesperson Alicia Trost told local ABC affiliate KGNO News.
