BART exists to transport people safely and efficiently. I think they do a fantastic job of it. They manage to make BART travel reliable, fast and safe. The presence of a strong and armed police force is necessary and fundamentally a good thing. If disrupting cell service protects riders, then it is the right course of action.

Or would you all prefer BART to protect people's right to tweet at the cost of lives and injuries?

BART rides trough some extremely violent neighborhoods, and carries all kinds of people, rich and poor. The fact that it works as smoothly as it does is a miracle already. Compare it with some of the trashier public transport options out there. Even some MUNI lines have some really creepy things going on on them.
