As far as I can tell, nearly everyone agrees that breaking the law when it is unjust is a good idea, in at least some cases. In the U.S., the illegal civil-rights marches and sit-ins now enjoy nearly universal praise (including quite a few retroactive converts), and the Boston Tea Party is even taught to schoolchildren in a positive light.

The only real disagreement seems to be over what injustices are serious enough to warrant such actions, not over the principle. And I mean, trashing someone's ship while disguised as a Native American, in order to protest an import tax, doesn't exactly set a high bar.
