The other day, some crazy woman climbed into a polar bear enclosure at a zoo. As might be expected, she was badly bitten before being pulled to safety. Her entering the cage made as much sense as civil disobedience by a small number of activists.
Such actions do nothing to further liberty. Those outside the movement-l-the vast majority of people--just watch the news. "Just look at those idiots! Thank God the police are around to deal with 'em."
One person disobeying a bad law, or even a handful, do nothing. Large numbers ignoring bad laws get things changed!
