As someone that lives in a third world country, I think that everything John said about the case (that it was about people wanting bribes) is true.
Also he said people hit him with a baseball bat after putting a helmet on his head, I know even other techniques (a cop friend told me one of the things his corrupt colleagues do is hit people with soap bars inside towels, it also hurts a lot without leaving bruises if you know what you are doing).
Do you remember the news about ukrainian authorities raiding the office of STALKER devs and demanding to be paid? If shit like this happened in Ukraine (which was a pretty stable country back then), then just imagine what scale of corruption is going on in countries like Belize.
That being said, the accusations that he killed his next door neighbor in Belize and then fled the country are disconcerting...
