An article from CNet tells of a dilemma caused by the anti-terrorism fervor in San Francisco.

Apparently, the fine folks in SF decided that sling shots were a likely terrorist weapon, so they banned them, leaving Sun's James Gosling (Java guru) without his traditional implement of T-shirt flinging at this year's Java One conference.

Fortunately, the folks who banned sling shots hadn't studied their history, and hadn't bothered to outlaw siege engines, so the crafty folks from Sun decided to roll in a specially designed trebuchet!
