I wonder how a sky marshal would have coped with a plane load of lagered up Celtic supporters...
Stand there and admit to being a ranger? Maybe even chant "Rangers.....Rangers........Rangers....urrrgh"
I believe one scheme at the moment is for the S/M to carry the gun in his hand luggage, and there to be some secret signal that the gate & Security staff will nod the bag through. Which means the terrorists would have to allow him to get out of his seat, take the gun out of the bag... Point it at them....etc..
nah. Not happening, is it?
