I haven't seen much except from the odd poster over on the Dark Side(DU, bartcop etc). However the black bloc is not going to annouce their intentions on a website, though you can check for the aftermath on indynews in San Francisco. They have posted pics before. The black bloc will definitely be there and make their presence known. They will have their agents in the crowd ready to pick up stragglers to run amok, inviting police response and arrest. Any Starbucks, McDonald's World Bank or INS office had better be prepared. These morons are actually hoping for a repeat of the 68 DEM convention in Chicago as a way of bringing attention to their cause.
2: How many FReeps have been relegated to certain designated areas due to security precautions? (NOT the ones where the anarchists already had the street, and FReepers needed someplace safe to counterprotest) I seem to remember that happening at several FReeps of Clinton.
Free speech zones became a way of life during the Toon administration. Even more despicable is Planned Parenthood using RICO statues to shut down pro-lifers.
I probably ought to mention here that if they were not allowed to protest at all, I'd be screaming my fool head off - and thinking "I can't believe I'm defending these creeps" - but if it's good enough for us, it's good enough for them.
