YES. Branicap has explained how Djindjic was shot. The Qestion No.1 is why his bodyguards and driver remained on the scene for 10-15 minutes instead of speeding off right away to the nearest hospital. Government building perimeter was covered with security cameras so there is no explanation why no medic team came to the rescue.
It seems that security umbrella was removed on purpose.
I wonder if they waited to ensure his death - the delay dimming any chance surgeons could save him. Or else the delay was to be positive that he was already dead. His killing seems to have been a planned inside job.
