>Who provides and pays for the service at the BART stations? If BART does, then I guess they have every right to shut it off if they like. If not, then disrupting somebody else's service should be a no no.

We, the cell phone consumers, are the ones paying.

>I wish the GO system (commuter train) here would shut down the service so I wouldn't have to listen to people making phone calls just to say, "I'll talk to you when I get home." Believe me when I rode the GO, I heard nonsense like that all the time. And don't get me started on people who are convinced that everyone in adjoining provinces want's to hear their pointless babbling.

Ya I just put on some headphones and attempt to ignore everyone else (well..except for the blonde girl that rides the same bus as me in the morning....hahaha)

>>>>>>>So cut off cell phone communications to quell a protest?? This IS the United States isn't it?

>>>Ah yes I see that they didn't JAM the signal - they simply removed the power to underground service towers...which I would *think* is still illegal - surely the FCC has such rules (I'm trying to find out).
>>>A government agency turning off mobile-internet and phone service to quash a possible demonstration — sounds familiar doesn't it? Just like the speech suppression used by Middle Eastern dictators to quell dissent. It's nothing more than unlawful suppression of First Amendment speech!

>>I was pointing out that it wasn't jamming, which to my mind is much more serious - in effect, an indiscriminate physical-layer DoS attack.

>>The possible legal implications are interesting, I agree. How about this scenario:
>>
>>- BART receives credible news of potentially dangerous protests
>>- BART considers shutting off cell service, but decides not to
>>- During protests, people are injured or killed
>>- BART gets sued for not shutting off cell service
>>
>>A couple of other things worth thinking about:
>>
>>- Metro transit systems are "soft targets" that are choice targets for terrorist activities
>>- My understanding is cell phones are currently the triggers of choice for bombs or other devices
