Here's an article from the Boston Globe about a woman, name of Needs, who was acquitted of assualt and other charges. She chased down some snowball weilding domestic terrorists and gave 'em what for. Then, she incapacitated a bystander whose car was blocked by her car.
A woman who testified for the defense expressed regret that when she herself was snowballed, she hadn't the stones to act. Quoth the article: "The woman told the jury she wished she had done what Needs did," a statement with at least two layers of meaning.
Favorite line from the article: "A lesser charge of carrying a firearm -- pepper spray -- without proper registration was dropped."
Throw of the snowball to (not at) Jim Romenesko's Obscure Store and Reading Room
