Factual error: Carrie loads a rifle with at least a 7mm Remington, possibly a .30-06 Springfield bullet. She shoots Quinn in the back one time, and he falls, only to disappear and reappear where he chokes Carrie from behind. He later removes his jacket to reveal he's wearing a soft armour bullet proof vest. The armour he wore was maximum level 3A vest which will only stop handgun threats. He would require a plate carrier with SAPI/ESAPI ceramic plates to stop such a threat. (00:55:37 - 00:57:10)
