Has the TSA even ever caught one terrorist? Serious question?
im not sure thats the idea behind it.
the usa has a force called jsoc to handle with terrorists directly.
the tsa is more of a prevention tool, to make things harder for them.
like ticket controlers in public transports, overall they will not be business effective, but theyll help to run the transport busines as a whole better financialy
and money, someones making money off of this.
but i hear the usa customs are nice all in all, much unilke the british,those are rude and cocky.
now as for pat powns in general,and scanners.the metal scanners have been around since my childhood,and pat downs too,not sure about usa,
