How does "This Is America" raise awareness for police brutality, racism, etc?

I'm guessing this is about the song by Childish Gambino

tw// shooting

It raises awareness by showing how media and entertainment muffle police brutality and racial injustices. This is shown multiple times in the video, first when Childish Gambino shot the guitar player and then immediately a dance sequence was shown. The dance distracts the mind from what just happened, and as time goes on, you slowly forget there was a shooting at all. Then, again, he shoots at a group of singers. This again is followed up by dancing.
The video shows how the human brain is easily distracted by and forgets real problems when entertainment is shown. Media outlets gloss over racial injustices and then move on to 'entertaining' topics to make you forget, sort of how a muzzle silences a dog.
