From the judges pov, it's good logic to prevent any record except theirs.
The more obfuscation,smoke and mirrors the better the chance the real bad guys stay out of it...
There will be neither justice nor professionalism in this case. (Like many before and no doubt to come...)
It's such a cynical disgrace to all except the victims and defendants who deserve so much more.
Conviction, penalty ( death or more likely life to demonstrate Thai judicial clemency ) a few easily ignored international ripples ( but none domestic ) and back to business as usual and more victims next holiday season.
This place is cursed.
Is the CSI LA guy still active ??
