Glanton gang's state-sponsored scalp-hunting contract
In 1849, the Mexican state of Chihuahua paid bounties for Apache scalps. John Joel Glanton's gang of American mercenaries, which the kid joins, took the contract and soon began killing peaceful Tigua villagers and Mexican citizens, because their hair could not be told apart from Apache hair at the point of payment. The gang was destroyed at the Yuma ferry crossing, and that episode shows how a bounty that pays for a proxy of the target (hair) instead of the target itself turns the contractor against the people who hired it.
