This may be a video of a police officer beating an unarmed man, but it was for all of the right reasons. This security footage shows a Subway patron choking, then an officer who was also dining there saving his life. Footage like this is just as valuable to watch as DGU footage because it shows how forceful you need to be to dislodge food from an airway. In all probability, you are more likely to need these skills to save a stranger’s life than to need skills with a firearm. Watch and see how it’s done.
