TSA a failure at every level: Security expert

Multiple failures by the Transportation Security Administration highlight the need for change at the agency, security expert Anthony Roman said Tuesday.

A new Department of Homeland Security Inspector General report released Monday found that the TSA had failed to identify 73 employees with links to terrorism.

The news followed last week's reports that checkpoint screeners at U.S. airports failed to detect mock explosives and weapons in 95 percent of undercover tests. That led to the reassignment of the acting TSA director, with the acting deputy director leading the agency until a new acting administrator was appointed.

Roman called it a failure at every level.

"Just about everything is going wrong there," the founder and CEO of the security and investigations firm Roman & Associates said in an interview with CNBC's "Closing Bell."

The TSA "simply needs new leadership, new executive management, a new training program, [and] better screening in terms of the personnel they're hiring."

Roman, who is also a licensed commercial pilot, has 37 years of investigative and counter-terror strategy experience and has testified as an expert in court cases.

During his work, he and his team have traveled with all sorts of equipment, and he said he hasn't been stopped once by the TSA.

He thinks one problem is that the job of a TSA agent is boring and involves repetitive tasks. Therefore, there should be psychological screening to get the right kind of person to be effective in that kind of environment, he said.

"You need repetitive training on an ongoing and frequent basis and most importantly to keep them on their game you need daily audits at different locations with accountability following those audits," said Roman.

However, airline CEOs think there is more going right than wrong with the agency, said Seth Kaplan, managing partner at Airline Weekly.

He spoke with them at a meeting this week.

"A lot of them said the TSA in many ways is the envy of the world, has been a leader since 9/11," Kaplain said.

While there are obviously well-documented problems, "a lot of them sort of said you know the old cliché, let's not throw the baby out with the bathwater … knock on wood, there hasn't been a 9/11 since 9/11 and that's not because nobody has tried."
