Forget El Al, the security at Indian airports is better.
As soon as you enter the terminal your checked luggage is X-rayed and sealed by security tape. Then you proceed to your airline counter. Your bags are weighed and checked.
Some airlines and most flights to US have bags X-rayed a second time. Not a problem as the gate attendant takes your bag to an X-ray machine which they have right next to do counter.
I know this sounds extreme but I checked in 10 bags (70 pounds each) and there was no problem.

They have been X-raying checked bags for more than fifteen years and they can identify stuff very well.

For Carry one..bags are X-rayed and then manually checked if something seems fishy. Pretty similar to here.

Personal checks- NO SHOE CARNIVAL.
Pass through the checkpoint if no alarm sounds your golden. Women needing secondary have a small booth with curtains so no one can see them being checked.

Recently I flew Air India from ORD. Just before boarding the plane, Air India employees were checking carryon luggage and travel documents. Guess they dont trust TSA.

If this is done by Indian airports and Air India, you can imagine El. TSA is still learning and will take years till they get they act together. Only problem is they learning curve needs to be faster.
