SF Bay Area Transit authority kills wireless service in stations to stave off potencial flash mobs

Very clever of BART. The protest/flash-mob/demonstration/riot that was feared and anticipated (in reaction to a BART cop's shooting incident)  never materialized. Hmmmm. Chicken or egg  conundrum here. Did the protest fail to materialize because cell phones were not working (cuz BART had wireless service shut off) or was the whole threat overblown in the first place? Who can say at this point? But still I'd look for this sort of reaction by authorities to continue. Because whatever the reason for it that's what they did and it appears to have worked.
