Lack of blood isn't surprising from an entrance wound, especially with someone wearing two layers of clothing and only being able to see the victim for about 4 seconds after impact. If the heart was hit, that would reduce or eliminate blood pressure almost immediately, which would lead to reduced bleeding.
Lack of muzzle flash doesn't mean anything. Video cameras do not have persistence of vision that is similar to humans so things can happen in between the frames and not show on the video. The human eye tends to hold images for a short time, so even very short events will show up in human vision, but video cameras tend to actually take instantaneous snapshots and then string them together. If something happens between the snapshots, the video won't show it.
Both the shooter and the victim show startle responses that seem pretty genuine.
But the point made above is really what matters. Whether the video is real or fake, the lesson is real.
