By the way, as of 9/11/01 it was NOT illegal to carry box cutters in your carry-on. So what exactly did the airport security companies do wrong?

Isn't it just plain convenient (and duplicitous on the part of those who continue to perpetuate the above myth) that we're blaming the airport security companies for a combination of failures by airlines (cockpit entry policy before 9/11), by the intelligence community and by the government at large (failure of imagination -- that some people would actually use commercial airplanes as missiles)?
