My first thought was to send in Seal Team 6 to make sure no other travelers fall into the same fate.
Then again, that would make every
village react this way when travelers came through, probably worse.
There must be some twisted logic in the villagers' actions, though, considering women and children were involved. Do they consider themselves legit police, and the resistant travelers fleeing criminals? The villagers must have experienced some serious shit to have come up with all the whistle stuff ahead of time.
Should those who encounter a situation like this just place themselves at the mercy of whoever they encounter in the jungle, and not resist? This situation sounds only marginally better than being at the hands of a drug cartel in Mexico.
At this point, Machu Picchu is off my bucket list.
