why are jails and prisons so scary?

In my experience, prison wasn’t really that scary. I was in a women’s correctional center for just short of a year and it was mostly just boring. I wasn’t ever really in fear. I just spent 23 hours of every day looking out on a gray hallway from behind some iron bars. It’s overwhelmingly dull, but not necessarily scary, at least for me.

they are filled with black people

The dregs of society are there, some worse than others.
