Integrity

Integrity (n.) A quality that all officers and NCOs possess in abundance until they make a career threatening fuck-up, at which point it goes right out of the window and they revert to CYA.

The hard right over the easy wrong.

Also one of the great clichés when the DS, noting that something awfully bad has happened, asks 'OK, integrity question: di you do it, Cotgrove?'. As a rule, answering yes will get you a punishment and the DS' silent, slight grudging respect, while answering no will get you and all your mates a punishment and the DS' eternal hatred. There's a right answer to this one.
