The very existence of any &quot;fast lane&quot; should automatically call into question every single security procedure that is disabled by the fast lane.<p>After all, there is not a single criterion for TSA PreCheck that couldn&#x27;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&#x27;t possibly come up with the cash.)  And so on.<p>Since someone with ill intent would clearly be capable of achieving TSA PreCheck status and bypassing some of the checks, the passable &quot;security&quot; checks therefore <i>must not be important by definition</i> and should be automatically discontinued.<p>The really sad thing is, I&#x27;ve observed that it bypasses the ultra-expensive scanners in most situations too.  So they&#x27;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.
