A top Israeli airport security expert says the new screening procedures being implemented by the Transportation Security Administration are a "hysterical" reaction to the terrorist threat.
Ben Gurion Airport's former director of security Pini Schiff warns that the TSA pat-downs and body scanners won't be effective in pinpointing terrorists.
"When you are wasting time and when you are wasting manpower and the level of service to the passengers is so low - something is missing in the way of finding the passenger you are looking for," he said.
"When millions of passengers are suspected, how can you find the one suspect passenger you are looking for? It's impossible to do," he concluded.
Schiff also says the new system will be impossible to sustain and said he wonders what will happen when it breaks down.
Israel, a world leader in aviation security, began implementing profiling techniques in the 1970s.
"What we do for many years is the questioning system," Boaz Ganor, executive director of The Institute for Counter Terrorism in Israel, told CBN News.
"The security personnel, the airport security personnel in Israel was trained to identify the suspicious behavior of people, to question the people and by the questioning to be able to find suspects," he explained.
Opponents of profiling say such methods could lead to religious or ethnic discrimination.
"We are not talking about discrimination," Schiff told the U.K.'s Sky News.
"We are talking about passengers who have to be checked differently to other passengers," he explained. "It can be a Jew, Christian, Muslim whatever."
Schiff said he hopes the U.S. will heed some of the lessons Israel has learned in its long battle against terror.
"I would suggest to copy in a way Israeli way of checking passengers in our international airport. It can be done."
