Upgrading the Prison gives you a delay in the time before you can execute a Commander, and level 21 gives a boost for the highest level of Commander you hold. Important for the stronger players who have the capability to capture and hold commanders. Less important for most players early on in the game and you might decide to wait with upgrading this building to higher levels until you reach the last phase of getting to Research Facility level 21 and can buy the required Golden Cuffs in bulk, which is cheaper. Prison upgrades can be done as soon as the Headquarters is upgraded.
