Without adding commentary you could also feature short clips of him on youtube demonstrating his behaviour. Him assaulting Sam in Thailand, going in a rage against a driver that overtook him safely, insulting his own girlfriend, attacking victims of horrible circumstances. They all speak volumes by themselves. I think having those moments readily available and prominently displayed on youtube would be good. Its pretty strange watching him talk about effective activism and being calm. When there are so many moments he has been psychotic and aggressive.
