Do authorities have a right to shut down cell phone service in the wake of flash-mob protests? Case in point: Bay Area Rapid Transit (BART), after a confrontation in San Francisco’s Civic Center station, sparking protests. Claiming public safety and fear of more protests, BART recently closed various San Francisco stations and disabled wireless reception, enraging passengers. Attorneys and co-hosts Bob Ambrogi and J. Craig Williams welcome Attorney Marvin Ammori, Visiting Scholar at Stanford Law School's Center for Internet & Society and Gene Policinski, Executive Director of the First Amendment Center at Vanderbilt University, to take a look at this new challenge to public safety and balancing First Amendment rights.
