I respectfully disagree with your opinion that her efforts will have no positive impact. What you may be trying to say is that her actions alone will not change the law, and that is true. It may also be true that she is a lunatic, but that does not change her status as a citizen and is, therefore, irrelevant. Since civil disobedience may involve breaking the law in order to demonstrate injustice, whether she broke the law or not is also irrelevant.

Rosa Parks has been mentioned before. Her civil disobedience was not the first of its kind in the fight for civil rights. It was not even the first of its kind involving the bus laws. She is famous for having been the last such incident before the Montgomery Bus Boycott.

I believe this woman's actions in demonstration against the TSA will be one of many that plant a seed. I also mention her because part of her story sounds eerily familiar.

"Two policemen came on the bus and one asked me if the driver had told me to stand and I said, 'Yes.' And he wanted to know why I didn't stand, and I told him I didn't think I should have to stand up. And then I asked him, why did they push us around? And he said, and I quote him, 'I don't know, but the law is the law and you are under arrest.'" - http://achievement.org/autodoc/page/par0int-1
