I've previously started several threads about the modern fact that state law enforcement prefers that we stop taking photos out in public (even though the state now has more cameras than ever watching us). Law enforcement gets all the more paranoid if you take photos of them out in public, as though citizens don't have the right to documents how the police, our public servants, are doing their jobs. I'm going to use this post as a place to collect incidents from the United States and from around the world demonstrating governmental intolerance of citizen photography. Here is a recent example:

A Facebook campaign is calling for people to boycott a shopping centre after claims a man was questioned by police for taking photographs of his own four-year-old daughter.
