I looked up the video, in case you're interested.

I'm pretty sure it's the one, I had watched. I don't want to watch it again, though. Still am shocked by it after such a long time.
If it is that video, it shows the entire scene & the video stops exactly at the moment, before they start shooting. So, you may see his last moments on YouTube, right before collapsing from fatal gun wounds.
The back story is basically, that some moron wannabe lawful idiot reported him to the police about a "rifle" he had, but in fact it was just a gun for playing around. He showed it to everyone & everyone was enjoying this fun toy. The moron wasn't at the party & literally assumed, that everyone on the party must be somehow part of the conspiracy, where everyone just blindly accepts a guy with an actual rifle. This is what the guy calling the police must've thought, else he wouldn't have called it.
Or he did not think at all. Most US Americans call the police whenever they don't understand something. They always presume the worst.
For example, there is another guy who literally walked on a car parking area, without going into a car, so the police was called on him, because it was "unusual". Things like these are the most US American shit there is. #FuckUSA
Well, anyway, I digress...
So, the killers arrive & put the victim into this stressful situation, as seen in the video. They were basically doing some Guantanamo styled power play, right there. So, of course, he made the mistake of moving his hand too quickly, which made the young officer fill him with bullets until the victim dropped dead.
Needless to say, the murderer was never in prison. He just changed his work location & still lives off US American taxes.
That's 'merica for ya.

....
Yeah, right, almost forgot my point.
My actual point was, that if this disturbing footage is perfectly legal & even available on a platform, which boss says, that the most important part of freedom of speech on the platform is to restrict content, then a screenshot portraying a horrible person, like the Discord guy, should be legal & you shouldn't be banned for it. Simple.
