BART and the Cellphone Kill Switch

Like the first essay, the problem here is a matter of cherry-picking constitutional doctrine and the resulting analysis. Turning a time, place and manner restriction into content-based prior restraint is easily done, by ignoring the legal distinctions. A mobile phone in use at the possible site of an underground demonstration may not seem to you like a bullhorn used on a residential street at 2am, but the legal problem presented is akin to that, rather than to the Pentagon Papers. Your preferred solution on rewrite of the first essay, to make the central distinction you had to confront a mere inconvenience on reargument, is not generally speaking a good idea, and wouldn't work here either. I think you have good arguments to offer, but your habit of beginning by cutting off your awareness of current law at the root is not the best way to develop them.
