Wasn't aware of that, but I don't think it changes anything. I don't want my view to come off US-centric either. No one is going to detain/imprison Tony Blair either. Nor Angela Merkel. Nor Jacques Chirac. Nor Gerhard Schroder. I would posit that the indictment of any head of state -- present or former -- belonging to a superpower would involved the explicit action of said nation, or at least the full cooperation of many other nations bringing extreme diplomatic pressure on the government. You don't just snag them while they're on a trip to your country.
