Responding to privacy concerns raised by travelers and civil rights groups, the Transportation Security Administration pulled 171 full-body scanners from airports last year.

The scanners cost a minimum of $130,000 each bringing the total cost to at least $22 million.



The Chicago Tribune reports that the TSA shipped 154 scanners to law enforcement agencies in Arkansas, New York, Michigan and other places, with 96 others remaining at the manufacturer’s warehouse.

The TSA now uses a different type of full-body scanner that alerts screeners about possible hidden weapons by showing yellow boxes on a picture of a generic, cartoon-like image.
