Oh boy... I just realized a couple of things.

(a.) This story is like four years old.
(b.) I may have been victim to fake news.

A couple videos now have me convinced the blood on the hero's chest appeared immediately after the cops shot the villain. Specifically this video, and tomo news suggests other people have that interpretation as well. If the cops are what killed that man, it's doubly as tragic, especially if it was covered up too. Who knows maybe he has bullets from both the bad guy and the cops, or maybe the bad guy had blanks?

UPDATE: Meant to insert this slow motion video.
