After reviewing the first hour of Dietrichs' last show, I discovered a few interesting things he said while attempting to "contextualize" his slandering of Peter Moon.
Before I publish what I found I have to say that it is my opinion Dietrich intended to manipulate Vinny Barbarick from the start. At this point, we have no confirmation as to Barberick's condition and are left, as always, to speculate on whether any of this is true.
Both are pathological liars and sociopaths with no redeeming qualities. Either Barberick has truly suffered a heart attack and stroke as Dietrich described, or has created a ruse to separate himself from Dietrich we may never know. It might also be a case of intended manipulation on both sides in which Vinny decided to finally abandon Dietrich after years of being abused and a lack of cooperation by Dietrich. Barbarick's questioning whether Dietrich was actually an SFD Police Officer seems to be one of the issues involved prior to the publication of the latest book.
