The Beeb have worked with that unit before, maybe 3 or 4 years ago?
The Hant crew seem to be pretty fair and reasonable on the whole, so being sensible is usually all that's required. Don't know what stance they'd take with the cameras behind them... do they adopt the nice/friendly/reasonable approach for the PR, or the hard line approach to give a very public warning?
I'll let you know how nice they are to me!
