Saw this dude in a tweet during the G20-Riots and thought „cool guy“, his story is even better:
60 year old historian Martin Bühler (who identified himself to the press, I do not identify activists without consent) appears to ‘photobomb’ a lot of media images of the G20 in Hamburg. In reality he is a long time observer documenting police brutality. In Hamburg he chose to cultivate the most non-activist ‘white bystander in a suit with a bike’ look he could manage and casually walked in front of police. As police slowed down or interrupted attacks and waited for the ‘bystander’ to get out of the way (being caught on camera trashing what look like bystanders is bad press after all), activists had time to regroup or retreat.
[update 17.7.] His Website supports his claim to be a historian, but it also supports claims in the comments below, that the guy seems to have a very own level of craziness if nothing worse.
