Solitary confinement for longer than fifteen days is literally torture as defined by the U.N.
Using that definition muddies the definition a lot.
4 years is definitely cruel and unusual imo. 15 days is whatever.
I just think they should have soft things and light etc in their cell if we're going to continue using that. A comfortable place.
I thought at first you were mocking everyone acting like stay in orders were any thing like solitary confinement. But your last paragraph throws that notion off.
