What I find interesting about the AIT scanners is there is no proof they work. The only people claiming that it is an effective screening tool are the DHS folks and the manufacturer. Congress refused to fund this when DHS first asked for the AITs.
But then along came the Recovery Act (aka the stimulus bill) …somehow they were funded in the ARRA bill.
In other words – the AIT scanners are the result of PORK spending.
Also of note – there is no independent testing of the effectiveness of the AIT scanners.
