BS. YOur “understanding” is wrong, and whoever led you to that needs to be raked over the coals because the information is readily available all over the place: They were retired law enforcement officials (police detectives) who had first been trained by the Maricopa County Sheriff’s Office and then deputized.
And if you had listened to the presser that you claim to be knowing about you would have heard Mike Zullo say they were only able to get the postal stamp that they mutilated in order to duplicate the draft registration’s forged postal stamp because they operated with the authority of the Sheriff.
This was a legitimate law enforcement body. All the excuses that “only nutjobs believe any of this stuff”/ “no credible authority has verified these claims” are unadulterated bullcrap.
Mike Zullo also said at the presser that for the first month of the investigation he was adamant that they were going to prove that what Obama presented was genuine, but that the evidence just wouldn’t allow them to go that way.
I've only heard about Mike Zullo, who is always referred to as a "detective," but one can be a private detective outside of law enforcement. Considering it's never been stated which department he worked for, I find this to be the most likely explanation.
