I say...more power to BART! But why just a station? In a station you can usually move away from that inane conversation that the participant thinks is so all important (but is less useful than tits on a boy). I say shield the cars people ride on and eliminate the idiotic conversations us riders have to endure.
"I believe that it was not allowed because A. someone might need emergency communications, "
:rofl:
That's a good one! What's 911 going to do that can't be done with the emergency system already in place? Answer is NOTHING. The real reason that jamming is being fought in places where it would be totally appropriate (transportation, theaters, some restaurants -- or anywhere else people should expect peace and quiet) is because it'll cost the carriers $$$$$$.
