— The Raleigh-Durham International Airport announced Friday the addition of TSA K-9explosive detection teams to conduct real time threat assessments to improve security.

The initiative is part of TSA's approach to move away from a one-size-fits-all model and closer to the agency's goal of providing the most effective security in the most efficient way, according to a statement released Friday.

TSA officer Todd Voorhis works with Evans, a dog names after a New York firefighter who died on Sept. 11. The team's job is to check for explosives and assess behavior.

"Ninety-nine percent of the people out there love the dog, but there is that one percent out there who are afraid of the dog," Voorhis said. "We just have to balance how close that dog is to the individual, but also allowing him to complete his job."

Sari Koshetz, a TSA spokesperson said the added benefit of the K-9 teams is passengers getting through the security line quicker.

"If the dogs and the behavior detection officers have checked you out, they may send you to the TSA Pre✓ lines," Koshetz said.

Passengers in the TSA Pre✓ lines will undergo expedited screening, which includes being able to keep their shoes, light outerwear and belt on, keep laptops in their cases and bags of liquids and gels inside carry-on luggage.

"I think you really want all precautions to be taken, as possibly can be, to keep you safe," said traveler Bem Maduoye.

Officials said TSA uses random and unpredictable security measures throughout the airports, so no one is guaranteed expedited screening..
