"I was ejected from a plane for wearing 'Suspected Terrorist' button"

The title says it all: In the US, you can be thrown off a plane for simply wearing a label that says "suspected terrorist". I know this because it happened to John Gilmore.

I found some debate about it online - on the one hand, he is very clearly pointing out how inadequate the so-called "security" precautions are, on the other hand, he is purposely pushing the boundaries until he gets people wound up - there will always be a point at which he'll succeed.

I actuall sympathise with him and applaud his intentions. I feel the urge to make a Suspected Terrorist line of clothing.
