Just noticed. If you're in Escape Mode and you try to kill a K-9 dog handler, make sure you kill their dog as well.

If you kill the guard and leave the dog alive, it will keep attacking you until you are dead, even when you are in custody! The dog followed me all the way to the solitary cell where it kept attacking until my prisoner was dead. Not sure if this is a bug or an intended consequence, but surely.... hmmm.

I'm not sure if it's my prison design but it seems pretty easy to escape, just wait for the main gate to open and the prisoner usually makes a dash for it in time. I can easily create distractions by setting fire to something near the main entrance, and when the firemen arrive, all hell breaks loose.
