prisoner in omegle

So like i met this dude on omegle and he's like in prison, apparently they let him keep his phone or smth (im not from america so idk how that shit is even possible) and he seems fairly nice. Got in because of self-defence (like what??) and idk what they feed these prisoners cuz apparently he has to fend for himself and get food himself or smth yes he's JACKED like bro HUH???? Idk I like watching prison documentaries and actually hearing it myself from someone is so cool.

and i got his username (somewhere) and now we're talking.

begs the question really how to prisons operate in different countries like have yall been in one?
