A man wearing a T-shirt depicting a cartoon character holding a gun was stopped from boarding a flight by the security at Heathrow's Terminal 5.(http://news.bbc.co.uk/2/hi/uk_news/england/london/7431640.stm)
Okay, I can see being suspicious about someone if they have a picture or phrase depicting a violent or offensive act, but honestly. If I had a Glock t-shirt on that shouldn't be considered offensive. If I had a picture of a person, neck in a noose, hanging from a tree that said "one less (insert racial category here) to worry about," then yes, that would be offensive/inappropriate.
The wearer, one Mister Brad Jayakody said "It's a cartoon robot - what threat is it to security or offensive to anyone at all?"
Yes, that's right. It was a picture of what looks to be Optimus Prime from the Transformers. Was he fighting Megatron? No, he was just standing there, weapon in hand. That's it.
A BAA spokesman said there was no record of the incident and no "formal complaint" had been made. "If a T-shirt had a rude word or a bomb on it, for example, a passenger may be asked to remove it," he said. "We are investigating what happened to see if it came under this category. If it's offensive, we don't want other passengers upset."
If I were them, I'd be more worried about pissing off a 40-foot alien robot that can camouflage itself as a vehicle.
