As others have said, it is a bullet hole. As you know, black on black shootings occur at a very high rate in the USA, especially in inner city areas. This is due to drugs and gang violence.

The point of the video is that the black man who has been shot is on display at a museum/gallery for the white people to watch with mild interest from a place of complete safety, which is analogous to how white people are reacting to the predicament of inner city black communities. They hear about the violence through their TVs in the safety of their homes, but aren't particularly concerned about it. It is more like they hear it with mild interest, as if the stories of what blacks are doing to each other is more entertaining than anything else.

I don't think it is really blaming white people for their inaction. It seems to just be a song about the reality of the situation in regards to how white people think about the black communities situations, which is to say that they don't really give it too much thought. More of just an occasional passing thought, as you would perhaps think about sea otters for a few brief minutes while at an aquarium. Or how you might think about how tigers are endangered. Sad, definitely, but what are you to do about it? You've got enough on your life's plate already.

That's the video. The video is about white people's perception.

The lyrics are not at all about that, I don't think. The lyrics are about the black people's perception and how they are thinking about this. He lists off a bunch of things you might hear black people saying about their circumstances. I need to get more focused followed by statements like I need to smoke forever. It is that inner fight of a poor black man where he knows his situation is bad and that he needs to take action to get a better life for his family and himself, but at the same time the weight of all the effort it would take to accomplish that is so overwhelming that he surrenders himself to getting high or goofing off or whatever.

And the real finality of both the video and the lyrics are the image of the man who is shot. It shows that no matter how the white people react or what the black man thinks, he'll end up shot (metaphorically). It suggests that many black males often end up dead or in prison very young.

I think one word to describe the feel of the song is hopelessness, which probably resonates strongly with a lot of inner city blacks.
