I am sorry if I wasn't clear. There are 3 entrances to the checkpoints at DEN: one where the regular, non status people go thru (where the randomizer was located), a clearly marked TSA Pre-Check line (which the randomizer emptied to if they got the correct arrow), and a CLEAR line.
Also noted was a special door for all identified aircrew that bypassed all the lines and machines. It was manned by a TSA worker. They opened the door for those eligible and it lead right to the trains that take them to the 3 concourses.
