Yep. Prison isn’t pleasant. Imagine that.
Our troops in nearly every single war didn’t have the luxury of changing their underwear twice a week.
Inmates at least have running water in their cells they can use to wash their socks/underwear.
If they can figure out how to make deadly weapons out of plastic coffee cup lids (Heat it over a flaming roll of toilet paper, roll it into a pencil shape, cool it by dipping it in the toilet, then sharpen the hard plastic on the cement floor) then they can figure out how to wash their underwear/socks in the sink and let them hang overnight to dry.
