You are then given by that publicly-funded employer time off to write (yet another) book based on the knowledge you've gleaned from your day job, i.e. the work the general public pays you to do and which you wouldn't have were it not for the general public. You then flog your book through (as you triumphantly tweet) "all good bookshops and websites" – not even offering a discount to the hapless licence-payers who've paid through the nose to make you the "expert" you are.
Nice work if you can get it, indeed. And if you've got it, then chances are you're Al Beeb's "Middle East editor" Jeremy Bowen, and you've started plugging your soon-to-be-published book about the Arab Uprisings.
Let's hope that the new book is not as laced with anti-Israel bias as the one you wrote about the Six Day War, and let's hope that you've become disabused of the notion that the Muslim Brotherhood is (as you once embarrassingly told us) a "moderate" organisation:
"Unlike the jihadis, it does not believe it is at war with the West. It is conservative, moderate and non-violent. But it is highly critical of Western policy in the Middle East."
Making value judgments of a reporter's own, even about those dastardly Israelis, contradicts the BBC's Charter and avowed commitment to impartiality, as I'm sure you know, even though you very often seem to need reminding...
And even though, unlike those who withhold the licence-fee, flouters of the Charter aren't liable for prosecution.
(btw, this is delicious!)
