Please, Your Tshirt is a Security Threat

A passenger has been barred from an International flight from Melbourne to London for wearing a tshirt which calls Bush "The worlds #1 Terrorist" on the basis that the T-shirt could have upset other passengers.

And to make matters worse:

Qantas issued a statement saying comments made verbally or on a T-shirt which had the potential to offend other travelers or threaten the security of aircraft "will not be tolerated."

Now how on Earth does this threaten the security of the aircraft? Is the Tshirt going to spontaneously combust in mid-air?

Still it is good to know that America's allies are standing proudly along side the USA as they fight the "War on Liberty" all over the globe.
