head or tail?

the american military is using a new-fangled lie detector in iraq and gitmo -- despite pentagon studies warning that the machine's chances of spotting the truth are worse than "flipping a coin."
what will this bring us to? a situation where it's: "hey pal, the machine says you're hiding something. might as well confess." those guilty will confess, but those not have also been known to "confess" under conditions of duress. the u.s. has got to do better than this
