In Pictures: Historian 'photobombs' G20 protests
A 60-year-old historian named Martin BÃ¼hler appears to have 'photobombed' a lot of media images showing police handling protesters during the recent G20 summit in Germany. Adopting a non-activist 'white bystander in a suit with a bike' look, he slowed down the police attacks on the protesters by blocking their way and providing the activists time to regroup or retreat. n
