OP, you've acknowledged that you're new here, so take this as gentle advice. There have been numerous threads over many years where someone said much the same thing: "Everyone complains, no one offers alternatives, what would YOU do?" and then people
have offered alternatives.
I suggest that you start by reading the most recent of those threads here:
Replace the TSA... With what???? from October 31 2010. As one example of good reasoned alternatives, in post 31 of that thread,
N965VJ has a comprehensive list.
Here's another thread from September 2010:
New TSA Administrator (hypothetical) where a number of good suggestions were made under an assumption that TSA remained a gov't agency.
Or this thread, from October 2010:
What would YOUR airport security look like? where, in addition to many many good ideas, is Post 22 where I list a bunch of
other threads on the subject.
That's three in the last few months alone.
I think everyone here agrees that there is a need for
reasonable, effective airport security. And I think we have provided LOTS of ideas for how to do it properly.
FWIW, my view is the same as MDtR-Chicago and Boggie Dog: WTMD, x-ray of baggage, and some means (swabbing, puffer) of checking for explosive residue, at least on a random basis. In fact, that's EXACTLY what is done in Australian airports for domestic flight and it seems to work.
