As was reported last week, the United States is now #47 in the annual World Press Freedom Index produced by Reporters Without Borders — not exactly a position which squares with the oft self-applied label, “Leader of the free world”!

Gavin Aronsen reports: On Saturday, Occupy Oakland re-entered the national spotlight during a day-long effort to take over an empty building and transform it into a social center. Oakland police thwarted the efforts, arresting more than 400 people in the process, primarily during a mass nighttime arrest outside a downtown YMCA. That number included at least six journalists, myself included, in direct violation of OPD media relations policy that states “media shall never be targeted for dispersal or enforcement action because of their status.”

After an unsuccessful afternoon effort to occupy a former convention center, the more than 1,000 protesters elected to return to the site of their former encampment outside City Hall. On the way, they clashed with officers, advancing down a street with makeshift shields of corrugated metal and throwing objects at a police line. Officers responded with smoke grenades, tear gas, and bean bag projectiles. After protesters regrouped, they marched through downtown as police pursued and eventually contained a few hundred of them in an enclosed space outside a YMCA. Some entered the gym and were arrested inside.

As soon as it became clear that I would be kettled with the protesters, I displayed my press credentials to a line of officers and asked where to stand to avoid arrest. In past protests, the technique always proved successful. But this time, no officer said a word. One pointed back in the direction of the protesters, refusing to let me leave. Another issued a notice that everyone in the area was under arrest.

I wound up in a back corner of the space between the YMCA and a neighboring building, where I met Vivian Ho of the San Francisco Chronicle and Kristin Hanes of KGO Radio. After it became clear that we would probably have to wait for hours there as police arrested hundreds of people packed tightly in front of us, we maneuvered our way to the front of the kettle to display our press credentials once more.

When Hanes displayed hers, an officer shook his head. “That’s not an Oakland pass,” he told her. “You’re getting arrested.” (She had a press pass issued by San Francisco, but not Oakland, police.) Another officer rejected my credentials, and I began interviewing soon-to-be-arrested protesters standing nearby. About five minutes later, an officer grabbed my arm and zip-tied me. Around the same time, Ho—who did have official OPD credentials—was also apprehended.
