The article is somewhat misleading. The system does not differentiate between Jews and non-Jews. It differentiates between Jewish Israelis and everybody else (including non-Jewish Israelis). Moreover, in itself it subjects nobody to any more intensive scrutiny -- it only allocates resources more sensibly.

It starts with the fact that no Israeli Jew has ever attempted to blow up an airplane (especially not a plane flying out of Israel). Therefore, while such a thing is possible, it is more improbable.

Each person is asked to show his passport. In fact, in the main departures area (not where LLM went) there are separate lines for Israelis and non-Israelis.

There are two different types of scanners for checked baggage. One is less expensive and has a lesser resolution. The other, conversely, is more expensive with a higher resolution.

A large percentage of passengers (most?) are Israeli Jews. Unless something comes up under questioning (like them saying they have been asked to carry something on board) their bags are sent to the less expensive scanners.

Israeli non-Jews (and they don't have to ask your religion -- the name on your passport will show if you are Jewish or not in 99.9% of the cases), all foreigners (no matter what their religion), and Israeli Jews who, when questioned, gave some answer that raised slight suspicions, will have their bags sent to the more expensive scanners.

Ironically, this form of profiling can actually work in favor of those sent to the better scanners. They take no longer, but they are more accurate and leave less room for doubt.

On one trip TLV-MXP, I was carrying a large bottle of body lotion that my girlfriend had asked me to bring. I was sent to the less expensive scanners, it could not clearly identify what it was, and I was sent to a second security person who opened my luggage to inspect the bottle visually.

Had I been sent to the better scanners I most likely would not have had to have this second check.
