In addition to despite the fact BART officials had previously said they would allow protests and freedom of speech demonstrations as long as they remained outside fare gates in the free speech area, I see they've now decided it's ok to detain members of the media and student journalists (who were all in the so called "free speech area"). This is explained by saying the cops didn't have enough time in the 'heat of the moment' to check the credentials of the journalists. Interesting that they still had time to handcuff and detain them..but not take the 1/2 second to view their press id.
