Yahoo says at protest in San Francisco on Thursday over a police shooting was intentionally hindered by BART turning off cell phone towers. The article says the towers were shut down for three hours.
The ALCU is getting involved with this and is not happy. They accuse BART of crossing a line by interfering with communications. Bart responds by saying it had the right to because people protesting would "create unsafe conditions for BART customers, BART employees and protestors."
Maybe someone should tell BART that discharging weapons in a subway is dangerous for customers and employees too.
