a tidbit over at social design notes about the greek protests sparked by the police murder of 15 year old alex grigoropoulos. there was quite a large visual response that accompanied a huge amount of protesting in the streets.
check out a collection of some posters here, and some interesting commentary about them here.
a good interview with alex's friend, who was with him when he was shot, is located here. tragically, it sounds no different from any other act of police brutality.
