Can the map tell me why this guy's wearing a pasta strainer for a hat? http://twitter.com/JohnPugh/status/426369689216745472/photo/... The riot gear I understand. The other, not so much.
The government banned people from wearing any form of headgear (eg masks/blalaclavas) during protests. Some protestors have been wearing silly things in their heads as a form of humorous defiance.
