Really; I thought after 9/11 this was all changed (remember the screeners waving the Arabs through after pulling them aside?).
Not the first, won’t be the last, I’m afraid.
Once the gangs work their way onto the ramps, be it Crips, Outlaws, Mob, etc., things get “interesting”, fast. Plenty of examples of this, going back 50 years or more, such as the JFK Diamond heists, or Drugs at Miami, etc.
It’s really up to management/Local LE’s to keep a lid on this kind of stuff, but sometimes, they’re in on it, too.
