NO ONE should be released from taking a polygraph test. It is my understanding that Federal Law enforcement officials are required to take polygraph tests periodically. Look at the traitors we have had in the past in the CIA, look how Snowden, who has given up everything to make sure that transparency to the public was given. Look at the Military General who was having the affair. Michael Flynn and Jeff Sessions. Look what Trump did too Comey when Comey stayed true to his oath. It is definitely a necessity that ALL are required to take a polygraph test.
