Earlier quoted context omitted.
Having just recently got out of jail, I can tell you it is infinitely easy to kill yourself. You would not believe the ingenuity of some of those attempts and successes. If the institution gets a hint that you are suicidal you will be placed in some sort of anti-suicide cell, which generally means that you are in solitary, you wear a paper or foam suit with no other clothing, you have no bed linen or any paper materi…
Such measures would make you want to commit suicide even if you weren't suicidal before.
I also failed to mention the light in the cell will be set to bright and will be on 24x7 and your cell will almost certainly have a completely glass door and you will be under camera and guard surveillance 24x7 to make sure you don't do anything stupid. If you are very lucky, some of these cells have a small wall in front of the toilet so you can at least get a tiny amount of privacy - they'll only be able to see you from the waist up.
