NOTE:This is just for the few people that dont know this.
What you gotta do is simple. Just save the game at the current moment you are in. Start a riot by locking prisoners anywhere, prefferably in the shower (they hate that) and start your riot. If you want to simulate a fire and want to see how it spreads and affect the prison system then put an power generator in any room of the prison, turn it on and have a squad of firefighters throw some water at it (this will make the generator catch fire) . What I do to make it a bit more realistic is once the fire started, I call the firefighters off and wait for them to leave, after they leave you call the firefighters again that will extinguish the fire.
Once the riot or fire is over simply load the game you saved earlier and you are back to your normal prison
