I 'spect their lawyers have advised that "Fraud" might lead them into trouble with the courts if this ever gets that far ~ though from the safety of Florida the "Red Tops" interviewing Mrs Canoeist are certainly creating enough ammunition for any defence barrister to be able to argue a case for dismissal of any charges that may be brought .... which may of course all be part of the plan. Devilish clever these canoeists ~ devious too. 
I have read this several times and still don't follow it. Please assist.
Confused of Tunbridge Wells
Did you watch HIGNFY last night? They dealt with your question and seemed agreed that Canoeist was indeed probably the best term to be used as any other description AT THIS TIME would either render the media liable to charges/court actions or be so long winded as to not fit the headlines. Merton, in particular, went into a lengthy rambling description of what the man could be called and came back to canoeist being the one most likely to be recognised by the public.
Meanwhile Mrs Darwin has fled Panama and is, apparently, enjoying the hospitality of a Florida hotel, courtesy of a UK Tabloid newspaper. where she is unburdening her soul to the eager journalists who are texting the copy back to the UK for publication. ~ See today's Daily Mirror, Sun, etc. No doubt the NOW will have it all tomorrow. Her revelations, now in the public domain, will surely provide any defence barrister, should Mr Darwin face charges, with many a legal argument about prejudiced juries, previous knowledge of the case by the aforementioned jurists etc etc etc. leading to a probable ruling that a fair trial is not possible or if one proceeds than they will use these arguments in their inevitable appeal.
I wonder if this is not a deliberate attempt by her to ensure (i) a continued flow of cash and (ii) to deflect or at least spoil any possible criminal proceedings against her and/or her husband. The newspapers, by carrying the stories from the USA, have presumably been assured by their lawyers that they are safe to conduct these interviews and publish them which would certainly not be the case were she in the UK at this time.
