That kind of thing is despicable. People who would do these things should be unwelcome on either side. Even if violence were justified in the current conflict, directing it at the machinery of democracy is precisely the wrong thing to do. If these are who the cops were trying to arrest a few days ago, they have my apologies and approbation.
(Unfortunately, what I'm hearing is that they spent their energy raiding a group whose role in previous protests has been to record huge amounts of video, which was later used to uncover police misconduct and clear hundreds of protesters who had been brought up on false charges. Politics and saving face seem to trump public safety and democracy here.)
Stories about the protests from either side seem to be coming out exclusively via blogs and YouTube; legitimate news coverage, if any, is local. To me, the actions and treatment of protesters are at least as interesting as what's on stage.
