Anarchists pose challenges to authorities

"Chief John Timoney of the Miami police, whose officers scuffled with anarchists during a World Trade Organization meeting last year and in 2000 during the Republican convention when he headed the Philadelphia police, said they pose a number of challenges to the authorities."

Isn't that, like, the point? What anarchist wouldn't pose a number of challenges to the authorities?*

*The answer: Those people are known as "libertarians".

(OK, I realize there's more to it, but if 10 angry libertarians want to comment, feel free.)
