Political protest is always slightly dangerous. And I feel the sit-in analogy is pretty apt.

But seriously, "the law is the law" isn't a great argument. Sometimes laws are bad. They need to be changed. Yeah, you can expect to serve some jailtime for doing civil disobedience, but that doesn't mean that they're stupid, what they're doing is stupid, or anything else.

You can still hold that opinion for other reasons, of course.
