I'm not sure that's how it would work. The ICC is in The Hague, which is where I believe he would have to be tried.
Then there's the issue of who would replace him? There is no freedom of assembly in Libya. Gadoofy has systematically rooted out and eliminated any groups of political opposition over the years. The people in a position to replace him right now are those who support him, new boss old boss kind of thing.
So before he's removed post haste, there needs to be a plan for interim governance while a fair election is held between a bunch of political newbs.
I would like to see the US and Europe apply pressures in ways other than military action right now. Freeze bank accounts. Identify several legitimate opposition leaders and provide financial support so that when, not if, Gadoofy is gone, the transition can be less chaotic.
Why should we get involved in Libya's internal problems?
To help get rid of a dictator?
Heck, there are several African countries run by extremely brutal dictators that are far worse than Gadafi.
Why don't we go in and help those people?
Oh yea, I forgot; they don't have oil and they are black.
