Proff that gun locks make life safe for criminals....this is so silly maybe I should put it in the humor form..... ANOTHER ROYAL GLOCK-UP Protection squad lose key to their guns case Norman Silvester Exclusive ELITE police guarding Prince Charles arrived in Scotland without the key to their gun box. The six-strong Royal Protection Unit left the keys on a desk in their London base before setting out for Holyrood Palace, Edinburgh, where the prince was staying with Camilla Parker Bowles during a week-long visit to Scotland. The blunder was discovered when officers went to open the box - containing Glock 9mm automatics, handguns, and rifles - in Holyrood. The officers from the Metropolitan Police had to borrow bolt-cutters from local cops to open the box - dubbed No. 1 case - before starting duty. A security expert said: "There were red faces all round when they realised what had happened. "They had to phone London and a desk sergeant told them the keys were still lying on the table." A spokeswoman for the Metropolitan Police yesterday said they did not comment on security matters. The incident is the fourth firearms blunder involving police guarding the Royals in just two years.
