Frosty P writes "Government auditors have faulted the TSA and its parent agency, the Department of Homeland Security, for failing to properly test and evaluate technology before spending money on it. The TSA spent about $36 million on devices that puffed air on travelers to 'sniff' them out for explosives residue. All 207 of those machines ended up in warehouses, abandoned as unable to perform as advertised, deployed in many airports before the TSA had fully tested them. Since it was founded in 2001, the TSA has spent roughly $14 billion in more than 20,900 transactions with dozens of contractors, including $8 billion for the famous new body scanners that have recently come under scrutiny for being unable to perform the task for which they are advertised. 'TSA has an obsession of finding a single box that will solve all its problems. They've spent and wasted money looking for that one box, and there is no such solution,' said John Huey, an airport security expert."
