Per https://www.yahoo.com/news/articles/fact-check-veteran-not-charged-070957126.html the video is complete bullshit, a mashup of various images and videos from all over the nation with no identified "veteran," let alone someone charged with murder for legit home self-defense.
BTW, "Stand Your Ground" almost never applies when you're in your residence, that's where Castle Doctrine comes into play and it's almost always stronger.
