German police is monitoring Facebook and has been for years. We once had a Conference at our University. Someone posted something about a party (back when everyone was afraid of facebook parties) and 15 minutes later the police arrived. They were not allowed to enter the premises, but by coincidence wink wink someone pulled the fire alarm in a then-vacant building 15 minutes later, which opened the gates and barriers for the cop cruisers waiting just around the corner. By coincidence of course.
