Reporter on the scent ofTSAcanine
washington » On a lateDecember morning at Reagan National Airport, a traveler in jeans, a striped shirt and winter boots passed a black dog sniffing a rack of potato chips. Seconds later, she heard the sound of toenails clicking against the hard floor. The noise grew closer and faster. She felt a wet nose press against her hand and watched a red rubber toy roll by. An exuberant Labrador bounded past her, retrieving his prize for a job well done.
Blue, a member of the Transportation Security Administration’s K- 9 passenger- screening team, had uncovered explosives strapped to the stranger’s back. Potential disaster diverted— all for a chew on a Kong.
“Dogs live in aworld of smell. This is their primary sense,” said DouglasTimberlake, aTSAexplosivesdetection canine handler whowas overseeing the day’s training session. “They have the innate ability to keep the public safe.”
Government and local law enforcement agencies have employed canines— and their superpower snouts— for decades. The TSA, for instance, uses dogs to inspect cargo, aircraft, parked cars, abandoned bags and other stationary objects found in and around airports. Canines working for Customs and Border Protection snuffle around luggage coming off baggage carousels, searching for such banned goods as fresh produce, exotic wildlife, undeclared currency and illicit drugs. And four- legged soldiers with the Department of Defense scour war zones for improvised explosive devices and other deadly contraptions.
Fiveyears ago, theTSAput its dogs on a newbeat: passenger screening. More than 140 of the canines preside over security checkpoints at over 35 airports. By year’s end, the agency aims to more than double the number of furry participants and expand the programtomore than 40 facilities.
The canines’ job is twofold. They seek out bombmaking materials on moving targets ( fed- speak for “people”), a gotcha that could require further investigation by TSA officials. They also help clear passengers for PreCheck, the TSA programfor low- risk travelers.
“We have cut back on general, random, real- time threat assessment,” said Timberlake, referring to the previously arbitrary selection of passengers for the fast lane. “These dogs are helping people get expedited screening.”
The dogs typically work the line during heavy travel days and times, such as the winter holiday period, and punch the clock for eight- hour shifts. To keep them on their noses, the handlers test the canines’ skills several times a week. They hide suspicious substances in trash cans, wheelchairs, prosthetic limbs and all manner of bags as well as under several layers of clothing. They also place the dangerous matter on civilian decoys.
“They’re finding stuff all the time,” said Timberlake, whowore a black shirt with a TSA K- 9 logo, “sowe knowthey’reworking and not just looking cute.”
The ongoing canine- training program is open to all federal employees— plus a few invited guests— who have a free morning or afternoon and no fear of dogs or hazardous materials.
I fit the profile. So for several hours, I played the wily fox in an airport- wide hunt led by GI Dogs.
The agency held the how- tobea- pretend- bad- guy lesson in a cramped, windowless room in the old wing of the airport. Before Timberlake suited me up, he reviewed some rules about the substance I’d be carrying.
“Please don’t eat it or stick it in your eye,” he cautioned, “because they are chemicals.”
He also explained the three variables— heat, friction, shaking— that could activate the element. I promised to stay 50 feet away from open flames, avoid fuse boxes and refrain from twitching. Then I signed my name to seal the agreement.
For security reasons, Timberlake could not specify the type of substance or amount used in the tests, but he would say that the agency samples dozens of explosives, including ones involved in recent terrorist attacks and attempts. For reassurance, however, he said that my chance of blowing up was nil.
He dropped the mystery block into a pair of nude pantyhose, which I tied around my waist like a leggy fanny pack. I threw on a jacket to avoid alarming other passengers.
En route to Terminal B, Timberlake explained how our sense of smell differs from a dog’s. If we pass a restaurant, for example, we can pick up the scent of a pizza. A pooch, meanwhile, can tease out the individual ingredients on the pie.
“They are smelling on a molecular level,” he said. “They can detect parts per billion.”
Before the outing, I had imagined amuscular guard dog with razor- sharp teeth tackling me like a rabid linebacker. However, Timberlake told me that the K- 9 team is filled with “floppy- eared dogs that don’t intimidate,” such as golden retrievers, German shorthaired pointers, vizslas and Labradors— breeds often found with Frisbees or sticks in their mouths. The four canines at DCA, for example, are all Labradors. Blue, Rufus and Kkirby are as black as licorice; Rriverso is butterscotch yellow. Other personal details: Blue served in Afghanistan, Rriverso is a graduate of the TSA’s first class in this field, and the two dogs with double initial letters were named after victims of 9/ 11. ( One hint that they aren’t your childhood snuggle buddy: the “DoNot Pet” sashes theywear.)
All the canines attend a rigorous 12- week course at Lackland Air Force Base in San Antonio, where they learn to fix on primary scents and ignore secondary odors. The dogs communicate their discoveries through passive response. They alert the handler of a possible suspect by approaching the person and sitting down or gazing at their master for approval— and the subsequent reward of a calorie- free treat.
“You can see that drive towork, find the explosive and get their toy,” said Mike Gapinski, section chief of canine operations.
For our exercise, I entered the gate area first, so that I could spritz the air with eau de explosives. Blue would enter several minutes later.
For the demo, the animal would pick up the scent drifting on the air current and follow the clues to me.
I set out solo, blending in with other travelers waiting for their flights. I passed a deli with an open cooler stocked with meat sandwiches. A rack of snacks stood within easy licking distance of a dog’s tongue. At the end of the terminal, I turned around and noticed Blue sniffing around bags of kettle chips. I passed him nonchalantly— nothing to smell here. A few steps later, I was busted.
If this had been a real scenario, two behavior- detection officers accompanying the canine and the handler would help assess the risk. Many finds are innocent. For instance, the dogs might stumble upon an armed air marshal or a sportsman dusted with gun powder residue from the range. Big takedowns are rare.
“No finds yesterday,” said Joe Havens, Blue’s partner. “It was a boring day.”
