Just copying my comment from the other thread, if you've ever flown to Israel, this wouldn't be a surprise to you.
The majority of flights to Israel will have some of their agents/ their police doing extra screening before boarding, asking questions about who packed your luggage, where it's been, whether you've received any gifts from anyone - those sorts of things, it's basically like a TSA screening. They've done this during more peaceful times so to see this continue now is hardly a surprise.
