Should prisons be racially segregated again?

I just finished watching all 4 seasons of Mayor of Kingstown, a show about a prison and prisoners in a company town where the company is the prison. It's fiction, of course, but as in real life, the prisoners segregate themselves along racial lines. Mostly the segregation is for protection from other races.

I did a little digging and found out that most prisons were segregated before the Civil Rights Act 1964, and then in 1968., when the SCOTUS ruled that segregated prisons are unconstitutional under the 14th amendment. I understand the court's ruling and agree with it.

BUT...

It seems like most prison violence is racially motivated. Would it make sense today to segregate prisoners along racial lines? Of course violence would still occur; they're criminals, after all. But it does seem like it might lower the amount of violence, and maybe even reduce the need for prison gangs.

Thoughts?
