Sure Truth, I'll try to be brief, but I probably won't be:
- he had an alibi (his wife likely wouldn't cover for him or probably wouldn't be able to keep that kind of a secret)
- he lacked opportunity (his wife was sleeping next to him, family in the house)
- he had an explanation for the calls, and the timeline of Diaz/Pak visit to OB and the Diaz/Pak call to CPH fits the explanation
- your interpretation of court docs that he was somehow criminally or civilly found guilty of gross negligence while medically attending to a minor is incorrect, based on my interpretation
- your interpretation of court docs that he was in some kind of drug rehab is incorrect, based on my interpretation
- my guess is that MG later misrecalled the last name of the "Rehab" caller
- according to police, MG never informed police of the "rehab" call initially, so assertions about CPH by MG need to be viewed in the context of a mother looking for swift justice.
- Mari and those assisting her (i.e., findshannangilbert.com) have never posted her actual phone bill to demonstrate the time/date and originating phone number of the "Rehab" call (which she claims was prior to the first call that CPH reported to 48 Hours). If Mari was able to demonstrate that CPH indeed called her prior to the first reported call by CPH, this would probably change my opinion on CPH.
Do you remember the article where MG went with some blogger to meet with CPH and his wife? They seemed like decent people, and they seemed empathetic. CPH has a family, he's community-minded. Without more actual evidence, at this point I think he just got really unlucky when he ran into Diaz/Pak and made those calls to the family at their request. The MSM storm took over and he got swept up.
And as for why he didn't take a lie detector test, it's because he's smart. He actually listens to his lawyer. If the DA came to him with some decent circumstantial evidence and threatened to charge him, he probably would take a lie detector test to help clear himself as a suspect and avoid being charged. But right now, he doesn't need to from a legal perspective since it can only hurt him. From a publicity perspective, its already about as bad as it can get, so there's no need to take any additional risk that you make things worse for yourself.
