There have been several documentaries made about tie-dyed fans of the Grateful Dead, following the band around on tour. The End of the Road was one such film. At one point in that movie the Deadheads stopped in Las Vegas before a show, and in the process of innocently enjoying the local sights wound up being brutalized by the police.

Speaking about that mistreatment, a bystander objected:

Don’t treat these people like animals, [just] ‘cause their hair is long and they smell bad....

That’s [how they treated] black people years ago. They’re taking away the most important right. The freedom of expression.

It was a black man who said that. And he’s absolutely right.
