The Israelis are the acknowledged experts and leaders at airport security. Do they engage in rampant TSA-like invasive patdowns of teenagers and grandmothers in wheelchairs? Last I heard, the answer is "no."
But we can't do airport security the way the Israelis do, because they focus their attention on people who might actually be terrorists. In other words, they engage in profiling and, as we all know, profiling is evil. Terrorists have rights, too, so it[s important for a terrorist to know that innocent people have just as much chance of being harassed by the TSA as actual terrorists.
