Really just seems like they're adding fuel to the fire. Its kind of a boneheaded move, as people will just organize the old fashioned way the next time around.
Just silly.
Just silly.
And many of them will be angry @ BART for disabling their ability to contact friends / family during delay, look up status and alternate routes on the web, etc.
wide ripple to heavy-handed tactics.
Now if you're stuck on a train in a tunnel because protesters are causing the system to shut down, that's a different situation, but still not decidedly evil or foolish for BART to turn off its cell service. In BART's defense, they did tell everyone earlier in the day to make alternate plans and prepare for delays.
I'm sure that more flowery rhetoric could be said about the whole business, but I'm going to go with:
Bad BART. Bad. Don't do it ever again.
