How about some facts, instead of all the bull ?
First of all, he was not sent to prison because of failed polygraph tests. He was sent to prison because he had been charged with aggravated sexual assault of a minor, and was allowed instead to plead guilty to injury to a child. He was convicted of a crime - without the use of a polygraph. That's why he went to prison. Period. The fact that he was granted probation to begin with is probably the only judicial abuse involved.
The revocation proceedings were brought because he failed to meet the terms of probation. The failures included failure to pay fines, as well as his being unsuccessfully discharged from treatment. So even without anything related to the polygraph, he was still in violation of his probation due to his failure to pay the fines.
Judges aren't required to grant probation, and they can set any terms they wish. , the word "probation" literally means "testing". It's basically a test to see of the criminal can follow the rules. No one has to prove that an additional crime has been committed. Associating with a known felon is not a crime, but can be grounds for revoking probation. The same for consumption of alcohol, possession of a firearm, leaving the county, etc. In this case, the judge actually made the polygraphs part of the terms of probation. If the guy doesn't meet the terms, tough . He can serve his actual sentence. You know - the one he got for screwing a child?
In this case, the therapist kicked the guy out of therapy because he didn't feel like he was making satisfactory progress. That's an opinion. He can use any basis he wants to form his opinions. He could just as easily said, "I did not feel that the subject was being sincere and honest in therapy sessions." He didn't need the damned polygraph. Is it unfair that one person can have that kind of power over the situation? What's really unfair is when a 40 year-old man has that kind of power over a child. This guy had already been convicted. You people are arguing over whether he should be in jail for it. Probation isn't a ing right.
One more thing. A lot of things that happen in these cases never make it into the court proceedings. They get suppressed - or waived, as in the unpaid fines. The therapist likely believed that this guy was gaming his therapy, and still presented a danger to children, and he used the 5 failed polygraphs as part of the basis for his belief. And it's just as likely that the defense seized on that one thing to try and find a way to keep the guy on the streets. Do people go looking for reasons to revoke probation, in certain cases. You bet your ass they do. And they should. In the case of a child predator, it shouldn't take much to give these guys the privelege of the prison sentence they earned.
Nobody is trying to make polygraphs admissable in court, for the purpose of conviction. Nobody is trying to make the opinion of a therapist, based solely on a polygraph, sufficient evidence for conviction. There's no slippery slope. There are enough other judicial and law enforcement abuses to get concerned aout, without blowing rthis one out of proportion.
