This is America reaction

Summary

  A old African American man walks to the chair to play the guitar.
The camera then zooms in to  Childish Gambino.
While he dances through the room, the man sitting on the chair changes to man who has a bag on his head. Then he shoots the mans head, after that chaos lurk thru the scene.


Symbol

The symbol of a man covered with a bag means that the man was abducted or has been taken as a hostage.

Another symbol is that after Childish Gambino shoots the man and the choir he dances jolly. That means that how America is trying to hide the shady side of the country.

Ironey

The irony is that after shooting the man and mass murder the choir, in the last scene Childish Gambino   gets chased by the white police man.
