Has anyone been stopped going through an airport because a sniffer machine or dog has picked up firearms discharge residue?.
I was speaking to someone the other day who had the airport sniffer dog take an interest in him.
It turned out that he picked up all his cases and put them in his Barbour jacket pockets...and he was wearing the jacket (no cases !).
It's something I've never thought of but as the equipment they use these days gets more sensitive.....
