Chapman embarrassed Mexican and American authorities. That seems to be his most serious crime. Also, whoever Luster was paying off down there lost a large sum of money when he was returned to the USA.
I think the authorities on both sides have much more to be embarrassed about than a criminal being kidnapped and turned over to authorities by a private individual.
However, bounty hunters are not above the law, and if they break them, they have to face the consequences like anyone else. The fact that they're chasing supposed bad guys doesn't give them any special privileges.
Dog's mistake was in failing to bribe the proper authorities before making the grab. On the other hand, he can probably get out of jail time in Mexico if he makes the bribes now. It will just cost him more.
FREE DOG !

I think this is the real reason. Luster is the criminal!
According to Dog, he was aware that bounty hunting is against the law in Mexico and informed and used a Mexican authority as an intermediary.
IIRC there was a criminal trade involved with this.
Exactamente, if you are a fugitive on the run in Mexico you are protected as long as you make regular payments. Miss a payment and they turn you over to the US. Run out of money and they turn you over. This cash cow had several years of payments to make before being turned over and the Government wants to take it out of Dogs A**.
