I agree with that your security was done correctly although in my opinion overboard.
But a friend of the family who is a 84 year old lady travelling to Israel to visit her son who at the time was working as a diplomat stationed in Israel was forced to open her private letters which security opened and had translated. After that they examined her body cavities by hand

Enough said.
I know the israelis are cautious and absolutely have the right to be but that's just crazy.
