This is classic projection on Vixen's part.
Whenever anyone looks at this case afresh, or stumbles on to it and sees for themselves that AK and RS are innocent and obviously innocent, then Vixen says they are, "merely parroting the FOA line."
With regards to Rhodes threat of physical harm, though, Vixen merely parrots the nutter line, that:
1) he's being misquoted
2) he's not serious
3) his threat is a typo
4) the threat has no force in law
5) the threat is a typical smear towards a guilter-nutter, who simply wants the best for Meredith Kercher
6) the threat is a hypothetical, and judges don't deal in hypotheticals
7) there were no bars on the lower window (while the person in question posts a pic which shows that there were/are.
My bet is that once the link is posted, Vixen will call it a hoax. The one thing that Vixen won't do, is distance herself from such threats, even if only in theory.
