Wow. Not surprised at all. When we took the port, there were a few of us who started chanting “Take-the-bridge! Take-the-bridge!” (referring to the Bay Bridge). We decided not to, but 20 minutes later, the entrance to the Bay Bridge was blocked off by the cops.
The week before at Occupy SF, every time we got word of cops on their way, we’d link arms and form human barricades around the camp. Every time, they backed off.
It’s been obvious that they’ve got insiders in the protests.
