Okay so this is not my personal experience but happened to my fiancée and I am seriously questioning the polygraph and the examiner's professionalism. So long story short my fiancée and I have 3 children total by previous relationships and one together  mine being oldest at 16 she has been a troubled child for quiet some time getting suspended at least once a year for fighting and has history of being a bully try as a I haven't been able to get her to change the behavior. So she got suspended for drug use/possession and as a result we took her phone and permit and grounded her for 3 months she was angry and kept insisting that she didn't do anything wrong and begged to not be punished and us allow her to go live with a younger couple until everything blew over of course the answer was no; I also added extra chores around the house well the next day after a long day of chores she claimed to have a headache and I went to shower while I was in there she snuck her phone and called the wife of the younger couple to pick her up and she ran away the bad part is she didn't just run away she went to the sheriff department and made allegations against my fiancée  (now keep in mind we have been friends for 24 years so this man is a person I know very well). As a result of the allegations he was cut off from his kids and I and made to leave the home. After aon that nd a half we finally started getting answers to questions about the case and he was asked to come in and take a polygraph so he agreed before he was even hooked up to the machine the control questions where asked to get a baseline they proceed to ask him a series of questions in different orders three times the sbi agent left the room and came back informing him he failed or spiked on some of the questions regarding the 16 year old so he starts to interrogate my fiancée asking him questions such as did he like blow jobs, did he have sex with our goats and pigs bc we own a small farm and repeatedly told him in these exact words he was a f**K up and that he f****d up, that the 16 year old was beautiful and if it was him he'd do her and did blame my fiancée if he did, this went on for four hours finally my fiancée had had enough and told him that it was time for his visitation with the children bc this has beenough going on for 3 months and he has had a total of 4 one hour visits with the children over the course of this investigation. IIA very disappointed in the sbi agent and it is my understanding that they really are not supposed to ask questions that don't pertain to the allegations. Needless to say eventually he was charged and we both have been told it's bc of the polygraph results bc without them they had no probable cause to arrest and charge him. They used what's called a totality of circumstances to get where they wanted to be in our case. And to top things off the Sheriff pulled the interview tapes from that day and said there are places where there are 4 second gaps through out the taped polygraph which seems suspicious even to him bc it's like the tape had been turned off then back on to get what they wanted. This has caused our family to distrust the sheriff's department and it's not just the adults it is the children as well I am just very distrustful and hurt that a sheriff's department would allow this king treatment to be imposed on the public! Also the polygraph is how dss has came to the conclusion to find us guilty as well even though we have not gone to court yet they also use terror tactics by threatening to take your children away if you don't do as they say this type of terrorism needs to be stopped they essentially wage war on innocent people.
