From our files 50 years ago: The Scottish Police Federation. The Police Act, 1919 outlawed police membership of unions and created the Scottish Police Federation which explains the second motto:
Blazon: Azure, three fetterlocks in pale Argent accompanied by two sprigs of thistle, slipped and leaved of the Second, flowered Gules, a chief chequy Argent and Azure.
Those splendid police dogs are blazoned:
Two Alsatian hounds, langued Gules, gorged of collars and with chain leashes reflexed over their backs all Argent.
