I wouldn’t be surprised to find out the cops and soldiers are moonlighting as avocado thieves to supplement their government pay. Seeing as they are already “armed” and “well organized”.
Add “wide-spread corruption within their ranks” and “their regional and national governments couldn’t give two shits that their shipments of the fatty fruit are routinely pirated” and it seems even more likely.
Dirty cops and corrupt governments don’t work hard to investigate the crimes they are committing. They will work hard to cover them up, however.
Money, money, money. It brings about such wonderful things.
