In my opinion, the entire security system that is set up is a joke anyway. We're all forced down the same security as passengers, and then watch the TSA walk thru the metal detectors, because they've had "more background checks".
Everything needs to be changed from the bottom up. I also see both sides of the argument of why FA's should be allowed thru KCM, and really don't have a strong feeling either way. I feel bad when they get their nail filers taken away, but like others have been saying, there is no "risk" if they get caught. If a flight attendant is fired, oh well, they lose a job. If a pilot gets fired for the same reason, that's thousands of dollars of training that they've pretty much thrown away for the rest of their careers/lives.
