Your post and the one you replied to nail Thaksin's cojones to the floor, so no need for repetition about economic crimes.
Those of us who lived here during his time in power will remember some inconvenient facts that the Kool-Aid drinkers either don't know or choose to ignore.
The egregious corruption of his administration pales beside the drug war massacres, one of which resulted in 2,873 Thais dead in three months, from February to April 2003.
The victims included whole families, women, children and old people.
That was from just one relatively short period of time. How many died in total on his watch is open to conjecture.
When UN sec-gen Kofi Anan nominated a rapporteur to investigate these gross human roghts abuses, Thaksin's angry response was "the UN is not my father".
He will never regain power in Thailand. A civil war would result if he did.
