As someone who used to visit the west bank for work I've spent many hours in intimidating interrogation, appropriated laptops, missed flights and most recently 3 days in a horrible prison without access to a shower or fresh clothing, after being denied access to the country for completely nonsense reasons. And the security argument is complete BS most of the time, NGO employees get the same kind of treatment.
The Ben Gurion approach really only works well if the border personnel likes you, A.K.A you're of the right ethnicity, which is not a shining example of how it's done right IMO.
