1) Don't commit crimes
2) Hope that you aren't a security guard
3) Run from lockdown
4) Flip out when we don't respawn
5) Think about what we did wrong
6) Repeat.
You realize that a jail is where people who have yet to be tried are held? No one in a jail has actually been proven guilty yet so any killing of them would be straight out murder. Not to mention 70% of people in jail do not actually need to be there.
I think what you are looking for is prison which is much different from a jail.
