I was thinking the same thing. Even in Dubai they barely use them and now you're telling me it's a common commodity for illegal miners in Peru. Ya right.
The miners are not Peruvian nationals. It takes a lot of capital to sneak into the Peruvian jungle and start mining.
I'm a bit dubious about the jetpacks but the rest - that miners are trying to scare Indigenous locals - is legit, and it's far from the first time this has happened.
