Maybe a missed opportunity?
You can't hide atrocities but you can certainly personalize them. Some of the most powerful write ups of mass murders have been a page with the picture and a short biography of each victim. This is so powerful because the victims stop being statistics and start to be people -- friends, neighbors, colleagues, and ultimately, any of us.
So I'd grab that video feed and add a commentary to it -- this 'thing' that he's just shot was actually a person with a name, age and a biography.
We also need to talk about the injured because apart from the emotional scars people who get shot and survive often have life changing injuries -- sure, they're not dead, but they're disabled for period of time, sometimes permanently. The so-called assault rifle is particularly dangerous because it fires high velocity ammunition; the bullet will cause capitation when it hits flesh which destroys a much larger volume of tissue than you'd get from a subsonic bullet.
