Revava actually has a former Shabak agent in it (Yisroel Meir Cohen).
And Chaim has questioned the actions of Baruch Marzel and Itamar Ben-Gvir after what happened with Roni. Chamish says Ben-Gvir is a Shabak agent. And Chaim exposed that they worked with Avishai Raviv, a known Shabak agent.
Yacov, everybody at Revava is a Shabak agent, starting at the top, with David HaOmo. That isn't any profound enlightenment.
Chaim doesn't think Marzel is Shabak though--just your typical scummy, opportunistic political whore. I believe that. What I want to know is why in the world HaRav Kahane (zt"l) hired this worm turd as his chief of staff. A rare but very, very bad lapse of judgment on his part. 
Yisrael Meir Cohen, worked for the police, was he in the Shabak? No one has presented any proof of that. Though Revava is certainly a worthless org.
On Raviv Chaim exposed nothing that wasnt already widespread knowledge, every Kahanist in Israel and most of the ones in the US knew that Marzel worked with Raviv, all the Kach people that Chaim supports, or supported worked with Raviv, this isnt some sort of great revelation, Raviv was supposedly Mister Right Wing in the early days of Oslo.
Rav Binyamin Zeev zt'l on the other hand ordered all of his people to not work with Raviv, because Rav Binyamin Zeev zt'l thought Raviv was either nuts or Shabak.
Marzel was the Kach spokesman, the Rav's chief aide in Israel was Mike Guzofsky, and in America Ken Sidman until Ken's death.
Though he had many "chief" aides and assistants over the years
