The hacker group Anonymous fought fire with fire against BART on Wednesday, posting a partially nude photo of a man they say is the transit agency's chief media spokesman, Linton Johnson.
Anonymous has been calling for the resignation of Johnson, who suggested that BART officials turn off cellphone service at underground stations earlier this month to thwart a protest against transit agency police.
The posting of the photo occurred as the BART board agreed to become the first public transit system in America to develop a policy regulating when to block cellphone service to protect public safety. It will take two to four weeks to craft a policy and discuss it with free speech advocates and BART's citizen review committee, officials estimated.
BART has been under fire from free speech advocates since the Aug. 11 blackout, which disrupted communication between organizers of a protest against the officer-involved shooting of a homeless man.
