It's attacking the service they offer. Actually it is more like attacking the regular folk who depend on BART to go to work and return home, rather than attacking BART itself. Not surprisingly, most BART riders are really pissed off at the demonstrators. The kind who purposely disrupt the lives of innocent people with their idiotic antics and don't give a shit about them. They apparently don't give a shit about the people who cannot afford cars and depend on public transportation to be able to work and live their lives. For this reason, I think trying to stop trains is even more despicable than trying to stop cars on the freeway. At least drivers have more options. Plus, there's the environmental angle. I don't use BART because I have to or because it's convenient for me. I use it because I want to do my bit for the environment. But if these assholes keep blocking it, then I guess my alternative is to drive and pollute. Look, as much as I really don't like to ride without my i-phone working, I think that's a very small problem, compared to not being able to ride at all because some idiots want to demonstrate by blocking the trains, and I'm sure most BART riders feel the same way. If you feel that an unjustice was made by BART cops, take it to the justice system, or stand by the BART stations holding signs if you must, but don't block the ********ing trains!
