I am deeply disturbed by what I learned today: that two passengers on the AA flight that crashed on the WTC were wanted by the FBI. They used their own true names and (probably) showed ID with that name on it.

So the new security measures are in. Hopefully the McSecurity folks out there (a joke itself!) will find all "toe nail clippers, nail files, knitting needles, twissors, scissors, any sort of hand help paper cutter, lighters, matches, knives and cork screws" so that I can be ensured a toe-nail-clipper-free cabin.

But WHAT is being done to ensure that there won't be any KNOWN AND WANTED CRIMINALS on board?

Even with a "flight marshal" on board, nothing will stop 10 suicidal criminals -- maybe the Air Force will shoot the plane down, but this is of little reassurance to us passengers. I've read nothing addressing how those hypothetical 10 criminals will be left behind on the ground, where they belong.

I have searched the net, but found no answers to this question, and am deeply troubled.
