If there is a streaker, its hard to kill them.
Tank was added.
Prisoners can get Baldr, Flak Cannon, C4, etc.
So cops get OSRs.
Jails that have a minimal amount of stuff in the name of being realistic are less fun in my opinion.
With Tezuni's, escape is possible, there are battles at the gate, and it isn't MP7 vs frying pan.
I like having a jail that is largely TDM based, because you get actual weapons and you have to find them.
Edit: Other than the random fetching and banning, I think the jail is a pretty balenced place.
