Nature of the threat

Qantas bans Bush T-shirt passenger:

Reading from a prepared statement, a Qantas spokesman said: "Whether made verbally or on a T-shirt, comments with the potential to offend other customers or threaten the security of a Qantas group aircraft will not be tolerated."

The t-shirt had a picture of the Lying Disaster Monkey and words suggesting that he was, in fact, the #1 terrorist. Take that, long-dead Osama!
