Just to be clear before I vote, in the OP, it says "alleged death" - based on prior reports, I'd thought the fella had died.
Anyway, if he is dead, it looks like the George Floyd defence is in play. A coincidental drug overdose at the time his air supply was being cut off.
Hope it doesn't fly.
This won't change anything in Thailand but it'll be interesting to see if they are brazen enough to give the guy a pass.
