Kind of reminds me of the Malaysian airlines flight 17, some Russian army guys (though vaguely not russia, just you know, those mercenaries who may be indirectly paid by russia, but not russia themselves) that had access to that BUK anti air missle launcher, that took down the airliner
In this case it's border patrol, a new toy, and a party balloon, but better I guess than shooting down the local crop duster
