At first, the guy from Genovese family gave demands to a guy from defenders side at the roof but he decided to run back to his friends with his gun out instead of leaving so he got killed. After that, one of them was behind us next to the stairs at the entrance of the roof but we did not realize he was from them at first so did not do anything to him but he started shooting us behind and started the fight outside at the roof. Then we went to the door to reach the panels but they direclty started shooting at us without saying anything so we shoot them back and killed all of them. So we did not kill them without demands, they started the gun fight twice already.
Lastly you mentioned wrong family name in your title, demands was given, also you started shooting at us first and gave us reason to kill you.
