I think lie detector tests can be useful tools in investigations, but they are certainly not infallible, nor are the results proof of anything. I can easily imagine an innocent parent showing deception on a question such as "Are you responsible for the disappearance of your child?" A deceptive response to "Do you know where your child is?" is more troubling, but who knows at this point if that is what happened.
DB says she was told she failed. Fox's MK says "police sources" tell her that DB "failed and failed miserably." Tacopina says LE never said she failed. LE says nothing.
I wonder if the attorneys arranged private lie detector tests for the parents. This is a common tactic. If the clients pass, attorneys are all over the news with the results. If they fail, of course nothing is said. I kind of doubt any private tests were arranged, simply because in high profile cases, unfavorable results always seem to get leaked or rumored.
What I find interesting is how the attorneys' seem to be telling whatever version of "the truth" fits the situation. When Picerno wants to paint the parents as unfairly targeted, they are suspects. When Tacopina wants to infer that police have moved on from the parents and are stalled in the investigation, the parents are not suspects. The attorneys' interviews are as confusing as DB's. The phones were restricted, they could receive incoming calls, but JI called home and was redirected to the Verizon service center.
Now Tacopina says DB has never changed her story although he has her "reflecting" (not remembering more details, but forgetting them instead) which says to me her story has changed. The Ambert alert info coupled with DB's subsequent media statements make me believe that her story has changed. Then there's the check up after 6:40 which is never mentioned anymore and bugs the heck out of me. The check up was either a "little bit later" or at 7:30, and if Shane's account is true, it couldn't have been 7:30. All MOO
