From the NY Times:
Some tourists, amateur photographers, even would-be filmmakers hoping to make it big on YouTube could soon be forced to obtain a city permit and $1 million in liability insurance before taking pictures or filming on city property, including sidewalks.
City May Seek Permit and Insurance for Many Kinds of Public Photography
Under the rules, the two or more people would not actually have to be filming, but could simply be holding an ordinary camera and talking to each other.
Ah, vague rules. The city's coffers love them, as do officers with ticket quotas...
Welcome to the communist city of New York, 2007.
