I must ask, do medium prisoners just not take/have contraband in a15? I know in a14, low prisoners were quite insistent on taking everything, repeat offenders, despite the multiple punishments. Quite the tunnelers too...
Something be wrong with my game or is this normal?
Maybe I'm making everybody too happy, but no one tried anything once I fenced off all my prison and managed to satisfy (most) needs.
Rarely, after visits, dogs will sniff out cigs or drugs.
I had medium prisoners at the start, once I was settled they didn't do anything
fun, so I changed to MaxSec prisoners and there was the occasionnal brawl at places where guards weren't stationed (had 3 showers and I just left cameras there).
After I stationed guards there too, some quick rare brawls would occur. I changed the food policy (more food/variety) - everything 100% peaceful, except for those new prisoners that may arrive already pissed off.
I think it's mandatory to have metal detectors on entrances to cell areas, so it guarantees that when prisoners go to their cells, they won't have tools or weapons with them.
This was enough to stop digging attempts since the beggining, I think.
One day there was no power for some hours, and a few days later a guy escaped through a tunnel.
Fences could have slowed that down but I forgot to build them at that point
A screen of my third (first successful) prison. I didn't use the west area because I bought it by accident after I finished it.
Also - little security science:
Shakedowns: it's funny to start one on work hours, so guards will confiscate the tools people are using to work with as if they were up to something. And doing it every few days (I do it on sleep hours) is useful to prevent digging and nasty fights. On my prison above I'd find only one prison keys and maybe a fork, but it was rare.
Bangups is very useful when fights start and may get into riots. I also experimented leaving maxsecs 3 days in bangups and could maintain control of them, even after releasing them from the bangup. No deaths and riots, at least.
Lockdowns is just bad. Leave it for a some hours and riots will begin quickly, and you'll probably only fix it with riot police.
