Anonymous denies it's behind the 'kill Facebook' campaign, but retaliates against BART

Does it matter that Anonymous didn't hit Facebook? When Bay Area Transit shut off cell phone service to prevent a protest, which Anonymous didn't like, it hacked BART systems and released customer data, more than likely data of some of its supporters. Sounds like asymmetric warfare to me. What does Anonymous care about a little collateral damage. As a commuter rail rider, though, I would not complain it all public transportation systems blocked all cell phone traffic.
