Agree with Dozywannabe,
The best play for Putin would be to dis-associate himself from the incident. Find the trigger-man/men and deliver them to the investigators. He has nothing to gain from this and surely no spin artists could turn this into something worthwhile.
Best play for Russia: Secure the corridor and area with the Polite People for the investigators. Deliver the perps. Get the investigators out of the area with the bodies and all remaining evidence. Carry on the blame game.
