The solution is not just "profiling". With all the personnel doing mindless dragnet of the entire traveling population, for the same price ($BILLIONS!), you look at passengers in advance; Arabic? Middle Eastern? Islamic ties? Travel history? When people arrive, they get scrutiny based on information provided to get ticket, as well as the observations of security personnel.
How about the Terrorist Screening Database (TSDB)? http://www.fbi.gov/terrorinfo/counterrorism/faqs.htm
The direct questioning of passengers is less through under our system that Israel's. Attempts to expand CAPPS and create what was known as CAPPS II were killed by the Senate in response to outcry from "civil liberties organizations".
However, we do have systems in place to look for people who's history and actions are suspicious.
Our government doesn't provide a lot of information on these programs and doesn't talk mention them more than they feel is necessary, but the programs do exist.
It's also misleading for the many people who complain about the physical screening process here and the list of banned items, to suggest that we should use Israeli screening procedures instead.
Israeli airports screening processes also include lists of banned items that are similar, and have similar physical screening processes.
They have similar prescreening databases.
What they have that we don't have are trained interviewers asking more in depth questions of passengers.
However, they don't skip the kind of screening that we have, they do that interviewing in addition to the type of screening that we implement.
