Although BART cop Johannes Mehserle was arrested yesterday, another protest is planned today from 4 p.m. to 7 p.m. in front of Oakland City Hall (Frank Ogawa Plaza). But wait, there's more! Some Facebook group exploiting the name of Oscar Grant -- hilariously billing themselves Coalition Against Police Execution (CAPE), because, other than a few nutty right-wingers, just who is FOR police execution? -- is asking you to bring a white t-shirt to the rally so they can help you create your own Oscar Grant T-shirt. It seems they also need money and food. Because at its core, tonight's protest is a party. You can go here for more details.
