How is this story related to these political movements you're describing? The events in the article seem like the usual robberies, unrelated to any political cause.
The alleged connection, if I'm reading GP right, is the shackling of police due to political pressure, and a more general breakdown in law and order. I'm not sure the Bart police are restrained from above, as it could also be a lack of resources that prevents them from patrolling the trains on foot. But a growing disrespect for the law does seem to be occurring in West Coast cities over and above what is happening elsewhere.

Is it not reasonable to hold the local government responsible for safety on the train? Given their track record for asking the police to be hands off, isn't the prevalence of unchecked crime in trains, crime on campuses and crime on the streets consistent with that track record?
A track record of holding police back from political protests isn't relevant. There's no political group supporting these robbers.
But even if there was this political motive to allow leftists to break laws with impunity, that has nothing to do with this story. This story is about run-of-the-mill robberies. Antifa doesn't run around robbing random people, and I don't think you'll find any influential bay-area politicians arguing against arresting people for robbery.
Sure there are. I know how to easily identify them, too.
If, perchance, one of the robbers is shot and killed while committing an armed robbery, look to see which groups are more concerned about punishing the shooter than blaming the criminal. Insofar as this is California, it will be a substantial list.
