Hummer Vandalized

This article is about a Hummer that was badly vandalized this week in Washington, D.C., apparently because some environmental activists thought that he shouldn't be driving it. One neighbor, who openly admits to not approving of the Hummer, called it a "hate crime," and thought it should be treated and punished as such. Ethically speaking, this is a case of revenge on behalf of the environment. But can we tolerate violent behavior that destroys the property of another in order to protect the environment? Shouldn't we try, however frustrating it may be at times, to work within the limits of the law to protect the environment?
