I'm not sure. As far as I can tell, he came on the scene a couple of years ago as an Iraqi expatriate who was in favor of ousting Saddam. He was quickly embraced by the right wing media and made the talk show and speaking circuit (i.e. appearing like a good guy). Only after the Berg murder did his shady past come forth. He was one of the most quoted in the media as to Bergs comings-and-goings, had access to his cell phone records, etc.
*IF* I were a skeptic, I might suspect that he was an infiltrator from the beginning. The Tridish and Tridish.com thing is yet ANOTHER coincidence that I'm having a hard time accepting.
I can't reconcile Aziz's apparent criminal history (plastic vials can be used for other things besides crack, however), getting busted selling stolen pc's, and his conservative political views.
He could have very well been an infiltrator. We Westerners have a disadvantage when it comes to dealing with the mindset and culture of the Middle East. The Tridish connection is just another disturbing coincidence in this mess.
It is notable that among the players in the newly free polity of Iraq are none other than the Iraqi Communist Party. It is possible, not knowing better at this time, that Aziz was / is actually a Communist.
