E
Early required - I am not trying to bash L.E. , just open it up for discussion and asking why not require L.E. to offend some family member by simply asking them to take a Lie test,( if no iron clad alibi, a gut feeling by L.E. , a tip, anything). Not that it will hold up in court, but that it could, could may get 1 bad guy even once to tip his hand by refusing and help help the direction of the search, I am not talking waterboarding and I often hear in cases "refused test" but is it or should it be optional or required before spending tax dollars on 11 agencies to search on day 6?
Requiring a polygraph would be a 5th amendment violation. You can’t make someone talk.
