With respect:
1) One can never "try everything". Someone can always invent some other security procedure. Heck, we're nowhere close to the real-life "
Con Air"; that's a whole bunch of procedures we haven't tried yet on commercial airline traffic.
2) Not everything is worth doing. We in the US had a marvelous Constitutional experiment with banning alcoholic beverages, for all sorts of good and noble reasons --- that ended up backfiring horribly.
3) Doing more stuff is no substitute for doing the right stuff. Whether or not TSA has chosen to do the right stuff ... well, that's obviously a matter of debate. But more isn't always better than less.
