The big one is "heartbeat detection".

"Tactical suggests there are 14 heartbeats in the room"

"During the interview the candidates heart rate increased during questions on their reasons for leaving the last position"

That discussion is illegal under current laws. (you cannot use a lie detector in interviews) Well at least in the US, check your local laws.

Authorities aren't restricted from using a lie detector in the US, just from using the results in court. They're frequently used to pressure suspects in criminal cases during questioning, knowing the results are inadmissable.

Gp seemed to be talking about job interviews. What cops can ask and what a potential employer can ask aren't the same.
