actually i didn't no anything about these black blocks guys before this post, but strangely enough i did notice a man sitting on the edge of the market putting a full ski hat (the kind that lets only the eyes thru) and a scarf over and around that. honestly i remembered thinking how out of place it was, not really knowing what was going on not to far away. now to read this post it's quite eerie, but the guy (while you can't really go on appearances anyway) was not that young, maybe about 30-35, and not a typical tree-hugger looking type although i'm not saying he looked a banker either-
