The very existence of any "fast lane" should automatically call into question every single security procedure that is disabled by the fast lane. After all, there is not a single criterion for TSA PreCheck that couldn't be met by someone wishing to do harm. Proof of citizenship, etc.? (Right, because none of the thousands of people currently in prison are citizens.) Fee required? (Sure, because terrorists couldn't possibly come up with the cash.) And so on. Since someone with ill intent would clearly be capable of achieving TSA PreCheck status and bypassing some of the checks, the passable "security" checks therefore must not be important by definition and should be automatically discontinued. The really sad thing is, I've observed that it bypasses the ultra-expensive scanners in most situations too. So they're essentially admitting not only that a lot of their checks waste time but that the things they spent obscene amounts of money on are also not necessary.
