Vichai N says it best:
"Let me add a few points that would suggest that Thaksin’s extrajudicial rampage was inspired by megalomania and that Thaksin was a psycopath. Thaksin is/was a well educated police lt. colonel, who possessed a Ph.D. in criminal justice from Sam Houston University at Texas, USA. And during all the time that the anti-yaa baa war was going on, from start to horrific finish, the FACE of this war had always been Thaksin Shinawatra(Thaksin wanted the glamor of the kill, so to speak) Thaksin Shinawatra therefore, by his police background and educational achievement, and by his position of PM of Thailand should have insisted that RULE OF LAW should be observed religiously while his war on drugs raged on. At no time, when the reports of abuses and extrajudicial killings were coming out did Thaksin hesitate to investigate or to ask for a pause in the killings. That famous “The United Nations is not my father” outburst of Thaksin Shinawatra was the highlight of exactly where Thaksin Shinawatra stand was in the extra-judicials; e.g., he wanted the Thais and the world to know he was the Maestro.
And further, Thaksin Shinawatra as PM of Thailand at that time, and possessing overwhelming unassailable majority in Thai parliament could have authored the most punishing anti-drugs laws, but DID NOT, but instead chose to deliver shoot-to-kill entertainment to the guillible Thai rurals. That certainly allowed Thaksin Shinawatra to feed his megalomaniac lust to be god-like . . . unfortunately at the expense of horrific carnage to many innocents"
