Colin Moyniha blogs for the New York Times:
When Occupy Wall Street protesters set up their encampment in September in Zuccotti Park, a new category of activist emerged alongside fixtures like meeting facilitators and medics.
The new participants carried laptops and cellular phones as they accompanied marches and wandered through Zuccotti Park, all the while sending a flow of moving images to computer screens around the city and beyond.
One of the first and perhaps the most prominent of those live-streaming the protests is a 40-year-old Russian immigrant and former derivatives trader named Vlad Teichberg. Mr. Teichberg started an Internet channel called Global Revolution TV, which has broadcast Occupy-related events from cities like New York, Denver and Oakland, Calif.
For months the so-called live streamers have complained that they have been arrested while documenting turbulent scenes pitting the police against protesters.Now, Mr. Teichberg is encountering a few problems of his own — problems involving a camera, the law and the occupation of a space –– in this instance, the first floor of a Brooklyn building where he lives and runs a studio used by live streamers.
