I agree that's not a great example from the perspective of what the individual should do. It's just the best example off the top of my head of an organization using its size to make lawsuits largely worthless as a remedy. That said, I disagree that Dr. Dao is responsible for the violence that occurred or that he chose violence. His was a classic act of civil disobedience: he simply didn't comply, even when violence was used against him, and it's turning out that the predicates for using violence against him are falling apart. He wasn't trespassing, the police acted incorrectly, the gate agents acted incorrectly, and the whole airline business leading up to that moment has built up a faulty expectation of what's allowed and expected. The Walmart equivalent wouldn't be attacking a floor manager, it would be staging a sit-in, which would be much more clearly a simple case of trespassing because it's a store rather than an airplane.
