I am curious which classification level they were keeping him at. John Gotti was kept in maximum security in order to speed up his demise due to health issues, with strong rumors being that he had been kept in a cell previously occupied by other inmates with infectious diseases.

A lot of prison and jail facilities are basically incubation pits for all sorts of infectious stuff that the hard living street people and very poor tend to take in with them. Cleaning supplies will be intentionally limited due to the use of some cleaning chemicals in improvised chemical weapons (like the old fashioned poison gas mix you get with bleach and ammonia).

The feds though tend to have access to what are considered slightly better in house clinics.

I think it was Mark Koernke who said something that the punishments in this world are often not for the evil that you do, but for the good that you do.
