This actually balances the game out a bit better than I expected. I was worried that the abilities of the Prosecution and Defense would imbalance things, but I realise now that a shrewd mafia will be able to close the case with some very well-planned moves before anyone knows what's going on.

Anyway, I have amended the rules in my very first post, and have also posted the victory parameters just in case anyone was confused.

Basically, it's either a mafia win, a town/lawyer win, a town/Defense win or a town/Prosecution win. I've got some narrative and images lined up to cover all the possibilities, so it's all down to how you guys play now. :3
