U.S. Senator Dick Durbin says it may be time to rethink prison policies about solitary confinement.
Durbin says the practice is increasingly used not just to segregate the most violent prisoners, but also to separate immigrants, children and gay or bisexual inmates from the general prison population.
While prison officials say inmates are segregated for their own protection, Durbin says the long hours in isolation create a higher risk of mental illness and suicide.
