At least one person's been arrested for keeping track of and publicly reporting police movements. Guy in Brooklyn who aggregated information on police movements around Pittsburgh during a protest, and Tweeted them: http://www.huffingtonpost.com/2009/10/04/elliot-madison-accused-of_n_309042.html http://www.huffingtonpost.com/2009/10/04/elliot-madison-accu... The charge seems to have been based on not the reporting itself, but a theory that he was conspiring with people committing crimes, like a lookout at a robbery. I wonder if it'd be on more solid ground if it were a website that just always updated with police movements, rather than only in connection with a specific event.
