If you can pick up enough powder residue on your shoes at a gun range to alert these dogs, I suspect there are going to be a LOT of false alarms, and consequently more excuses for the thugs to harass flyers. And note that they are doing this AFTER the checkpoint. Over time I foresee a lot of missed flight and unnecessary expense (e.g. overnight house, meals) due to disrupted travel post check point. People should be cleared at the checkpoint and left alone. And if a few unburned powder granules from a gun range set them off, a few ounces of powder dropped on the floor in the right locations outside security would probably keep these mutts tied up all day. Times Union: Whatever happened to ... It was nearly a year ago that the Albany County Airport Authority leased space to the federal Transportation Security Administration to house a canine unit. Now, the residents of the unit are ready to go to work. The TSA has several highly-trained Labrador retrievers who reportedly are even better than the best mechanical detection machines at finding explosives and other hazardous materials. And earlier this month, they demonstrated their skills."We actually did our first live operation with three of them on Dec. 18th," said Brian Johansson, the TSA airport security director at Albany. "They are checking passengers after the checkpoint." The dogs sniff the air, and during their first outing, one detected something and tracked it to an individual passenger. The dog had picked up traces of gunpowder. The passenger, it turns out, had been on a shooting range and picked up traces of the powder on his shoes.
