Re: Police would definitely use that information against them if they got the chance
Key thing to remember: The police are not barristers. They have a *working* knowledge of the law, but are not experts and aren't supposed to be.
Then they shouldn't (pay people to) be running their gob in public about things that they know little about and apparently cannot be bothered to look up for themselves or perhaps even seek some advice from actual barristers - before sticking their foot in it!
