Is there anything in that culture or society where this is a signal or sign for a killing with a message? foul play and this was their disrespect or message to others??????
I don't think so. Like most tourist spots, violent crimes committed against Americans are far and few between. Thievery happens all the time, but Id be willing to bet assualt and murder are pretty rare. From what Ive heard, most of the crimes committed are Thai on Thai.
I agree. I think he just got careless and paid the ultimate price. I also think there is a not so hidden joke in your statement that I won't exploit.
