SAN FRANCISCO – Transit officials said Friday that they blocked cellphone reception in San Francisco train stations for three hours to disrupt planned demonstrations over a police shooting.

This is a case of very sloppy, sensationalist, inaccurate and misleading journalism. Mobile phone reception has NOT been jammed.
What about other reasons to have our phone service on?
The FCC is reminding the public that such devices create "serious safety risks" by blocking access to public safety services.
There are NO 'devices'. Mobile phone reception has been turned off on the underground sections of the BART. A completely different thing. They're not blocking access to public safety systems.
If there is a emergency, no doubt the BART already has an existing
emergency communications system, as should all subways and rapid transits. These are usually in the form of clearly marked emergency buttons and intercoms in every carriage and other public areas.
If there is an emergency on the subway, like a fire on a train, where is the quickest and most knowledgable help going to come from? The subway's emergency communications systems. The person responding should have knowledge of exactly where the train in trouble is, and can direct help accordingly. Someone dials 911 on a mobile phone, and goes through to some call centre somewhere, they wont know exactly where the emergency is. Help will come much quicker by using the emergency communications systems, specifically designed for this purpose.
BTW mobile phones don't work on the underground sections of the London Underground either and never have. Only some subways and rapid transits actually have special extended underground mobile phone coverage,
which are there for the passenger's convenience, nothing more.
I actually had experience of an emergency on a subway last year, the Hong Kong MTR. Someone collapsed on a train, another member of the public got on the train's emergency phone, and was able to summon medical help directly to where the train was. Probably because the person answering the emergency phone knew the exact location of the train, presumably they where in the MTR's control room. If they'd used their own mobile phone,... 'Someone has collapsed, possible heart attack,
we're on the MTR somewhere.'
