The video shows 1, possibly 2 (If one considers how the water looks before the hit), big blasts, while fire from a submachine gun as seen would have made many smaller splashes. The color of the water and the ambiance in the parts before/after and during the submachine gun footage is clearly different, also the direction in which the shooter fires compared to the camera is completely wrong compared to the footage where you see the gun supposedly hitting the man.
