Here is an aspect your vid doesn't mention, that the 'car-bomb' was actually a missile strike considering where the attack took place. The 'car-bomb' was supposed to have been parked at the location of a 'secret meeting' 3 days prior to the explosion. I'm pretty sure those especial areas get 'examined' prior to any big-wigs showing up and car bombs would be detected. A vehicle that has a homing beacon would not be detected. There have been enough picture of missile strikes in Syria to show the 'hallmarks' of such an attack. One of the photo sets that match the pattern for a missile attack being made to look like a car bomb was an assassination that was falsely blamed on some Syrian Generals. Guess who coaching the 'false witnesses'?
Car bomb my ***.
Russia won't leave until ISIS is finished and that is over the airliner that was crashed. That and a defense partnership with with Syria and Iran. The war against ISIS doesn't have to be won overnight, take away the finances and moral support and it slowly dies all by itself after that.
Here is a system that can hit a secure area and the method of delivery can be lied about. Leaving a car-bomb in place for 3 days before it is detonated is a high risk maneuver, a missile is almost real time as far as planning goes and it's arrival is invisible to the naked eye. Damage to vehicles taht show the impact from above is the best trace evidence that a car was not the location of the explosion.
