The city of NY is planning to regulate the public use of photography.
Thhe reasons are commercial, the city wants to regulate (or calims it wants to regulate) public commercial work ... use of public spaces for makign movies, commercials, etc.
Fine enuff, but the effect is censorship. The impact of public photography on free speach has been enormous. There is no better evidence of this than the insisteance in fascist countries of regulating use of the camera as tightly as regulation of guns.
