Why is Thaksin interrogating Sivarak in the Khmer prison?

What's Thaksin Shinawtra doing in a Cambodian jail?

Questioning Sivarak Chotipong, the suspected "spy," to find out who was behind it all?

But interrogating a released "spy" wasn't supposed to be part of the deal. Besides, Sivarak had insisted all along that he had not stolen any confidential document that could have affected Thaksin's personal safety. In fact, he had said that news about Thaksin's plane's landing in Phnom Pennh had already been reported by Khmer media at least 20 minutes before the first secretary of the Thai Embassy there had called him.

So, the inevitable impression of Thaksin's appearance in the Cambodian prison yesterday was that he wanted to be physically there to confirm that Sivarak's release was due to his own "heroic" action -- and to squeeze any information at all from the alleged spy to feed his Pheau Thai Party to grill the Abhisit government in a no-confidence debate.

After all is said and done, it's all part of a well-scripted episode from the very beginning.
