The stated goal for the day was to "move-in" to a large, abandoned, building to turn it into a social and political center. It is a long vacant convention center - the only people ever near there are the homeless who use the space outside the building as a bed. The building occupation also draws attention to the large number of abandoned and unused buildings in Oakland. The day started with a rally and a march to the proposed building. The police knew which building was the target, surrounded it, and used highly mobile units to try and divert the protest. After avoiding police lines, the group made it to one side of the building. Now, this is a very large building, and we were on a road with construction fences on both sides, and a large ditch separating us from the cops. The police fired smoke grenades into the crowd as the group neared a small path around the ditch, towards the building. They declared an unlawful assembly, and this is when the crowd broke down the construction fence. A few people broke fences to escape the situation, others because they were pissed. A couple more fences were taken down then necessary, but no valuable equipment was destroyed. They only things broken were fences.
