I think the waffly answer is de rigeur because that's what they do.
We are left with perming one possibility from about four by my reckoning [for the waffly answer that is]. The question is why would any one of those wafflibilties be a better bet than the others?
Remember Bob Dylan and Robert Browning on what they meant by what they had written,when asked.
The answers were remarkably similar, synthesing and paraphrasing it summed up as:
"God knows I have forgotten already but you make it mean whatever you want it to mean"
Waffle would seem to be the option of choice, and that's certainly what I've noticed in a number of cases, but not in this one (at least not at the time of the most recent pressers on the case).
Anything could change, obviously, and if ever it turned out that any of the T9 were involved, then I expect that there would be a PR egg-on-face removal unit to deal with it.
On the other hand, and bearing in mind that the UK does actually give thought to media relations, progressive cop speak waffle could have covered all bases. So far, I can't see any evidence of that.
Strategy debriefs provide an interesting insight, IMO, even if they have to be couched in gentle terms.
