The following tweet maps show the distribution of tweets at various times during the night of 14th of November and the early morning of the 15th of November during the police raid of Occupy Oakland. The pattern of tweets show how the group was able to keep its cohesion and unity as the police carried out their raid, and how it was able to rapidly reform as the police left. This kind of smart crowd can effectively undermine much of the ability of conventional police methods for stopping demonstrations.
By early morning the police had left, essentially taking a few tents with them, but the Occupy demonstration reformed in the same area. You can see clearly from these tweets that the area has been refilled by protesters and bystanders looking at the protest site. The area around the camp is the only area of very heavy tweeting in all of Oakland and since police don't generally tweet while doing a raid we can only assume the Occupy movement in Oakland continues, with a few less tents.
