An interesting web site.....

The odd thing is despite the courts ruling over and over that there is not any general prohibition on photographing buildings, public or private, the cops still act as if there is.
Also, and I think this one may have made it to the Supreme Court, citizens are allowed to video cops during an arrest etc. Despite that, cops keep violating the law with seeming impunity unless the citizen is willing to stick with a law suit.
