BLOOD WARNING + SHOOTING - Guard vs rogue attacker

Not really sure the story here but the guard was quick on the draw.
By the time you see the attacker in the video till the guard draws and shoots, was less than a second.
Without audio and the guard going off camera, hard to tell how many shots were fired, one was definitely in the neck of the attacker which eventually ended the threat due to loss of blood.
It just goes to show how many shots are needed to stop the threat, he was bleeding like crazy but was still able to shoot at the guard at least a few more times.
Hope the guard is ok?
