I once had a case of a brilliant bank robber who held up a building society in 'wealthy but retired' Frinton-on-Sea.To do the job he put on full leathers and a full face helmet and rode a bike with false plates and made a speedy getaway.Perfect. All of the eye witnesses were unable to give any description, except that he was of average height and covered in dark leathers, save one old dear who said " I noticed only one thing which I thought was odd. He had 'Johny G' in studs on the back of his jacket". The police were so fast in getting to Johnny G's house that he was still counting the money when they burst in.
Not to mention the Irish cheque forgers who numbered the cheques in sequence, but not of the cheque numbers but the account numbers. Or the bank robbers who not only took the car of the father of one of them, who promptly reported it stolen, to do the raid. They also found that nobody had brought stocking masks. They stopped and bought two pairs of tights. There were four of them. They had nothing to cut the tights, so they drove off and bought scissors. Three rushed into the bank, collided with each other in the doorway and fell over. By this time the police had already seen them go around the bank three times in the reoprted stolen car and pounced.
