It is not very often when I am secondary screening. When I was flying out from ATL-TLV in summer 2006. When private screening was gave me secondary screening before enter the gate area. It was very tight security when they are searching everywhere at the gate. What is so special security for LY?

What is reasonable why security need gave all passengers need searches again at the gate before when they are get onboard the aircraft. Could you please explained something to me about subject secondary screening for TLV flights?
