Illegal wire tapping is what he did. He listened in on police and media without permission during an investigation of the Monster of Florence murders.
This is not about "inventing elaborate and improbably theory".
You employ an odd double standard, otto.
In the case of Amanda Knox, your posts insist "once a liar, always a liar." You refuse to acknowledge that perhaps she was under intolerable pressure in a foreign country and working in a language only somewhat familiar to her. As far as you are concerned, AK's lies show her to be capable of anything, including murder.

I, on the other hand, expect higher ethical standards from an experienced professional. And I certainly think that inventing an improbable conspiracy in one case may show an inclination to do so in another.
