Please descibe what El Al does (with some detail).
TSA focuses on keeping dangerous things off of airplanes.
El Al focuses on keeping dangerous people off of airplanes.
That being said, El Al also matches luggage to passengers, and pumps all luggage down to set off any barometric triggered bombs.
I bet if you objected to the search TSA would let your luggage make the flight without you just to further inconvenience you...
