Even though, as we saw in images of last Monday's riots, the APC's appear to have a capacity for spontaneous combustion that is quite on a par with the political situation in the British sector.
True enough, I too would have cut loose with the Raden cannon and lets see who thinks its a smart idea to chuck a petrol bomb at an APC after that*, but its not like you to take a metaphorical shot at squaddies being very careful to avoid civilian casualties at some risk to themselves?

(*not really. I might have squashed a couple as I drove off though)

I don't really understand your analysis of the sovereignty point. Immediately after the defeta of the Iraqi regime, sovereignty was being exercised by the allied forces, in accordance with what I understand are well known laws of war. As sovereign authority the forces issued a law governing the status of their members. So far so good. Any law that Mr Hussein's regime may have had on the issue is necessarily impliedly repealed.

Soveriegnty has been transfered to "the Iraqis". Still, OK, that will not of itself negate the law. And, finally, the body able to exercise sovereignty on behalf of the iraqis is not yet fuilly constituted. So as I understand it no one has/is yet able to conclude a proper visiting forces agreement. Therefore the interim arrangement stands as the last valid act of a sovereign authority in iraq on the subject.

Whether any of this is a good idea is a different issue, but jurisprudentially it seems to hang together. Though someone seems to have nicked my public international law book and the fact I have only just noticed shows how often I have to look any of these things up...
