I took a polygraph for my first real job while still in HS. I was a nervous wreck! I showed deception but was allowed to explain it afterwards. I got the job. I don't think I would ever take one for LE though, I really would be a nervous wreck!

being a nervous wreck doesn't preclude anyone in failing a LDT. I don't know of anyone who is calm, cool, and collected taking a LDT (on the inside anyway).
You also said you showed deception, but explained it afterwards. So I'm going to assume the LDT was correct in picking up deception?
If I read that wrong - I'm sorry.
If the mum failed her LDT and LE is treating her like a suspect - I think we're probably talking about something not easily explained away...KWIM?
:seeya:
MOO
Deborah Irwin says police told her she failed a lie detector test and are treating her like a suspect!
