(For those not aware: Israel got caught cloning passports of Brits travelling through their airports for identity theft purposes, despite the fact they had made an earlier promise not to do this again)

Specific statements which I am refuting:

"but the profiling is mostly behavioural" - behavioral profiling is secondary to the racial stuff. At the end of the day, a screener here is more likely to forgive some quirky behavior on my part because I am white and Jewish. Obviously, I have no hard science with which to back up this claim. My anecdotal sampling of friends indicates that their skin color and racial origin played a pretty immediate part in their scrutiny, since they tend to be geeky and harmless just like me.

"It's also more or less impossible to distinguish (visually) Israeli Arabs and Sephardim/Mizrahim." - As I said in the post, this isn't true. Even if it were true strictly on a visual basis, there are other cues to go by beyond skin color. And regardless, the screeners know the difference as soon as a conversation begins -- so what's the point of this statement?

"You're not going to get hassle for having darker skin." - again, no way to directly prove/disprove, but my anecdotal friend-experience says otherwise.

You are correct about the self-fulfilling aspect; if I was an Israeli Arab flying out of TLV, I'd probably be worried that they're gonna gestapo me in a closed room. Particularly so if I know that I'm not any kind of terrorist, and have no fondness for interrogations.

My personal impression from countless times of passing via TLV is that the profiling is mostly itinerary based. That is, Israeli citizen going off to a 3 day business trip to Europe is less suspect than an American tourist with a very short length of stay.

I know a middle aged WASP lady (pasty white, dignified, looks like someone who might be related to the Kennedys) who had to endure questioning because she fit the latter profile. Not really "gestapo", though - from what she told me it sounded better than the normal treatment non-US citizens get at Newark. Many of my Israeli family & friends are dark skinned, never had any trouble.

I'm not saying I know better, just that my anecdotal evidence doesn't match yours.

In any case, this isn't really applicable for the US. TLV gets much fewer visitors than JFK, and they tend to fit certain trip profiles - few people just go for a weekend in Tel Aviv, for example. Also, many in Israel itself are unhappy with the breach of their privacy, and my impression is that security procedure are actually moving to more reliance on machines than humans.

That said, the people were truly polite. If TSA employees were more tactful and friendly, that unpleasant potion might at least go down a little easier.

I don't think they really suspected me of anything, as a white Jewish kid, but I'm not very religious and maybe my answers to their religious questions while claiming Judaism as a religion was a red flag.
