The ACLU has been doing great work on this front. However you feel about "toughness" on crime, we should all agree on an upper bound to punishments.

I Spent 16 Months in Solitary Confinement and Now I’m Fighting to End It

I was just 17 years old when I was sent to solitary confinement in “Camp J,” one of the most severe lockdown units at one of America’s most brutal prisons, the Louisiana State Penitentiary at Angola. I languished in solitary for 16 months.Back then I didn’t know that Louisiana was the solitary confinement capital of the world. All I knew was that I’d been convicted of a crime I didn’t commit, and I had to maintain my humanity in one of the most dehumanizing places on earth.
