A man on Facebook by the name of Durwin B. Brown shared a post stating that he witnessed Denzel Washington get out of his car to help a young black man that seem to be in distress and in a situation with the LAPD. Denzel (or look a like) helped calm the man down and became a saving barrier between the civilian and the police officers as the situation could've been deadly had it escalated.
Whether this man was Denzel or just his look a like, it's clear that this man is a hero.
