The last I've seen about it was in late APR:
Rudy worked for the Perugian justice authorities. He murdered Meredith Kercher while under their employ and protection.

Waterbury hasn't posted anything since then on his blog so he's probably busy with his vertical gardening projects or perhaps lazily dreaming up excuses for making a wild-eyed assertion without a scrap of evidence.
Bruce still has the whole article embarrassingly featured at his site--the same site he said contains no false information:

Chris has allowed comments to remain in his blog about the case since late April without any opinion by the publisher himself:
We are both equally troubled by the “Guede as police informant” theory.

Perugia-Shock has allowed comments to remain too:
What’s really the reason behind the deliberately conviction of two obvious innocent: business as usual, face-saving, Guede a police informant,…?

That one is in the style of the JAQ technique favoured on conspiracy theory forums.
Tacitly or openly, two of the chief propagandists for the FOA have allowed Waterbury's claims to fester. Charlie's FOA site still links to Waterbury, too. These three JREF posters should take the effort to divorce themselves from such unsupportable allegations by cleaning Waterbury from their links. This will prevent those who rely upon their advocacy sites for their information from concluding that they have no case.
