Warning! A human does get shot in this video. Watch with your own responsibility.
People already accuse CIA for this (mostly the socialist people in my country).
If I had to choose between the two, I would say this is a inside job, pretty standard in Russia, they just need a reason to start shooting.
Now with the facts
Rumour tells it's a Turkish police officer. If that's true this is going to be one hell of an ride.
