And then there was the chap that thought it was a good idea to rob the bank on station in Germany, done during an NBC phase, he walks in with mask on, points gun at staff, fills pockets and respirator sack with dosh and then departs to blend in with everyone else carrying a musket and wearing NBC kit and Respirators....... The perfect crime..
His one failing, he never removed his name tape off the pocket on his NBC suit...
