[I have no idea if this is true, so I would take it with a grain of
salt. In particular, I wonder about whether the ability to actually do
what has been suggested even actually exists. On the other hand,
developing technologies to do things like this is eminently feasible,
and a discussion on technologies like it might be interesting. --Perry]
As police moved in to shut down the Weedstock Festival before the
Memorial Day weekend, cell phones used by the organizers ceased to
function. These were on systems from various providers.
Phones belonging to "anonymous" attendees, and major media continued to
function. I therefore presume monitoring beforehand.
Recalling Police complaints in the media about how well World Bank/IMF
protesters were organized with cell phones, I'm wondering if this was a
rehearsal for selectively shutting demonstrator communications at
upcoming protests at the Democratic and Republican National Conventions.
I'm seeking info on how this might have been accomplished at the
technical end, and as to the legalities.
