OK, I've said this before, but I'll say it again...
They call the first FC victim not because they are a security risk but because they are there...how "secure" the next few passengers will feel to see some rent-a-wander going through some poor schmuck's dirty skivies in search of a nail file...and once they are finished with that one, pray to God you are not the next in line because you too will get it....
APPEARANCE OF SECURITY/AWARENESS OF SECURITY...we should all repeat these meaningless phrases over and over as we give up more and more of our rights for the opportunity to spend hard earned cash to fly.
