Russian bird!, thats really odd. Plenty of US in and out, usually just before a protest gets suppressed somewhat violently. The protest in Canberra, at the war memorial is an example. 300 plus heavily armored 'police' showed up to quell the protest and fired upon the civilians with non lethal (?) 40 mm rubber rounds. How the Aussies let that slide is beyond me. But I have since learned the the federal government have passed legislation that allows foreign security forces to 'assist' Australian law enforcement. Stinks of the UN as far as I'm concerned.
