I'm the original poster of this (stating for continuity) and I am leaning toward him being innocent at this point. For a couple of reasons, mostly being the locals testimony and his access to the ability to expose what is notorious about the PI. Another suppressed, poor area, like Thailand, where foreign people come in and take advantage of easily buy-able loyalty, etc.
There is more to this. Even if it is unrelated to anything super important like Paddock or current happenings. It may actually be an example of causation. Because "we" are taking higher note and fighting back, "they" are taking out our own soldiers. His case being brought to light on Fox leads me to believe he is a good guy. they would dig a little before they ever let her on if he had any real connections to bad guys. Someone would have tipped them off to steer clear. They are corporate owned, after all. Still digging and appreciate everyone else doing it too.
The PI is so well know, like Thailand, like I said, that most people just shrug at the headlines. If he was making a documentary or bringing new light to something we just sort of take for granted is happening there, he would have been in danger, and he knew it.
The reverse to that is if he was truly guilty, those guys are cowards and don't fight usually, but the justice system there is literally third world low tech and corrupt, so getting the truth will be difficult for his family.
