What we have here is the TSA admitting that it doesn't need to extra-screen SSSS people to ensure security. Then why do we have the SSSS system at all? It's completely unjustifiable harassment of the paying, flying public.
What we need to do is shout from the rooftops and get some major press coverage of the fact that if people see gate screening, that means the TSA has just let SSSS people waltz on by in the regular line at the checkpoint. Then the ignorant fly-once-a-decade fear-o-philes will refuse to fly whenever they see gate screeners.
We can pit the nervous ninnies against the TSA!
