>Common sense has.....has finally vanished from the UK
Dont talk such utter rubbish.
We have people in this country who in the recent past have blown up planes, buses, and trains. They have driven cars into airport terminals and more.
For this reason we now have police walking round airports with guns, and these people are ready to shoot anyone who they believe MAY be a terrorist.
If you are a policeman at an airport there are thousands of people coming at you from all directions. You are trying to keep an eye out for anyone who may be carrying a gun or a bomb.
A hundred yards away you see a guy in a white T shirt, with what looks like a gun held to his chest. You shout for him to drop his gun, he does not realise he is the one they are talking to so does nothing, so the police shoot him as he seemes to be armed.
Things like this have happened in the past.
It was right that he was asked to change his T shart, and how anyone can be stupid enough to wear any clothing with a gun on it in an airport must be pretty stupid.
