Video purporting to record shooting of survivors after the crash.

I believe that there was a related post that an Australian news magazine was running a story that the Polish Officials where murders PRIOR to the flight taking off, and that there are no pictures of them boarding the plane. This would mean that the people being shot in this video where decoys dubbed into flying the plane. Also the report stated that only one ambulance was dispatched.
