America probably turned one of the russian agents, sending them all back together muddies the water and might make it harder to figure out who is the turncoat. Either way, it seems funny because if there is any speculation that one could have been turned then they all will be out in the cold anyway, so whatever is happening here is going to involve something happening quickly as they are all burned.

It could be a smoke-screen that hides something else that has happened / will happen somewhere else in the system?

That 'limited liability' will no doubt come in handy when they start throwing old people down the stairs and hiding their medicine.

The link to the pictures of the robots seems to be wrong, or has it moved?
