It's obvious. The harder you make it to down or hijack a plane, the fewer downed planes you will see. It didn't have to be perfect to prevent and deter. Some security is better than no security. If you had no security at all you would see planes go down all the time.

And it wouldn't surprise me if some of the detection technology were classified.

It would not be "great" if governments were more open about their detection capabilities; that would cause more terrorism attempts and is one of the stupidest things one could do here.

You know that TSA fails in 90-95% of cases and that crowds before it are a much jucier target?

Have those crowds been targeted?

I see similar crowd densities all over the place. I can think of easier targets than the airport.
