I'm skeptical on two counts; the first is that PreCheck aims to expedite screening by not requiring the time consuming AIT scan (especially when it seems that a majority have false positives that need to be patted down anyway); the second is that many travelers, myself included, use PreCheck to actively avoid AIT. If we are all told to use it anyway, people either will no longer bother to sign up for the program, making it redundant, or they will opt out more regularly than the average pleb, making the line run slower than a regular line. Or they'll just pick up on what I've been doing for years - wear a sling bought at a pharmacy and get a medical opt-out.

Then again, the TSA isn't exactly an institution enamored with logic or sense. If the corruption in Washington wants them to find an excuse to buy more machines from a lobbyist's friend, that'll take precedence over, y'know, safety and justice.
