Gee, thanks for the warning !
I don't think that's entirely fair on Neville. It looks like she is simply calling it how it is. Saying that's the bullshit excuse she's being fed, it doesn't fit with what else she had been told, but what would she know, she's no expert.
I actual prefer my politicians to say "fuck knows" when they don't. Far better than making it up as they go along.
