Maybe this has something to do with the high murder rate in Venezuela:
8 injured after anti-Hugo Chavez march
When the country is run by a tyrant he silences opposition by making them disappear. Venezuela is on it's way to being the next Cuba under Chavez and useful idiots like Sean Penn and Danny Glover are down there kissing the guys rotten communist ass.
Maybe Sean Penn can sign up to Chavez's Che Guevera.
