Police
in New York City aren't known for their respect of civil and
constitutional rights. You can be arrested now for the made up crime of filming cop. Well, cops are also taking cameras. Flux Rostrum is a filmmaker who was filming a protest against the Mexican consulate in NYC, over a murder in a Mexican city. Rostrum was jumped  by police and indeed, a NYPC captain who shouted "I want that camera."

Did the captain try to get a warrant to search or seize the camera?
No, in today's world, warrants are an option for many police, not a
necessity. When Mr. Rostrum went to complain at a police station, he was threatened with arrest by a police lieutenant! So much for public service.
