@hawkeye10,
I think that before he does all that, he should write chapter and verse about where all the metaphorical bodies are buried, and distribute copies of those to various legal eagles around the world, with strict instruction that they should be put into the public domain should he fail to report his whereabouts on a regular basis
The western spooks would love him just to appear and give himself up without any forethought. He would be instantly disappeared before he had a chance to make his case.
