My info said he would be charged in Thailand for offences allegedly carried out in 2003.
So he might not get to Canada.
TV news (BBC or CNN, don't recall which) said that too, and mentioned a possible 20 year sentence.
Canada wants to extradite him. What about Vietnam and Cambodia? Presumably if the Thais have charges pending, those get dealt with first. But then what? How would they decide who gets to extradite first?
