Some of you hardlines probably won't like this, but this is from the movie Blindspotting and it is about a black man on probation that witnesses a cop kill an unarmed black man running from him.
Each real life situation is different, some justified, some not. Nonetheless, this is a great and powerful scene from a great movie. You kind of have to fastforward the first minute and a half.
The context is that the black man that witnessed it is a mover and he happens to get called to a job for the police officer who, iirc, is essentially being driven out of town for that action and receiving threats.
the scene is essentially a freestyle-ized rap and I think that adds to the originality and beauty of the scene.
