I did a quick search through the archives and came up with similar stories for the airports at:
Houston: Dozens Arrested In Airport Worker Sweep
London: Illegal immigrants arrested in British airport security scare
and Los Angeles: Over 80 Southern California airport workers arrested
I'm sure there have been a few others as well, but this Denver bust seems to be one of the bigger ones.
Hope they keep this up.
It's nice to see a crackdown on this breach of security.
