SF subway sets rules for cell service shutdowns

The San Francisco Bay Area Transit District adopted a policy today that bars officials from interrupting cell service in subway stations except in "extraordinary circumstances."

The policy, which is believed to be the first policy governing intentional cell service disruption in subways, comes in response to a public backlash over BART for shutting off cell service to head off a protest this summer.

Under the new policy, BART may temporarily interrupt cell service only when it determines that there is "strong evidence of imminent unlawful activity that threatens the safety" of passengers, employees and the public, or if there is a threat of destruction of property or a substantial disruption of public transit services.
