Keen security personnel at Birmingham International Airport ordered a man to turn his t-shirt inside out because it bore a drawing of two crossed guns.
Staffordshire design engineer Dave Osbourne was wearing a Guns N Rollers t-shirt.

Guns N Rollers are a team in "an all-female roller derby league located in Portland Oregon", according to their website http://rosecityrollers.com/rosecityrollersgunsnrollers.php

Their logo is a tribute to that of hard rocking, hard drinking, legendarily fractious LA band Guns N Roses.

As he waited to board the flight to Newark, New Jersey, guards told Osbourne the graphic represented a security risk, and could upset other passengers.

The 21-year-old said: "I am all for extra security, but this was just plain stupid."

Bosses at the airport apologised, admitting guards "over-reacted".

However, something altogether more sinister could be at work here. New Jersey is, of course, home to card-carrying poodle rockers Bon Jovi. We therefore suspect the airport security men working the passage to said Garden State are in their employ, discharging an old grudge against Axl Rose and Co. for putting the Golden Age of Spandex out of its misery.
