You act like there's always 30 cops 24/7. When I normally play, it's cops who get outnumbered. There will be times when cops are superior and there will be times when rebels are superior.
I'm not advocating for a rule that dictates the number of civs that can be at a major crime and I'm against any sort of ratios/limits for both parties but that's a discussion for another time.
In that video, you break roleplay multiple times by mentioning the gods and the rules. If you want to have a hostage roleplay situation, have a hostage. It's that simple. Yeah the cops could have handled the situation better, but all you were doing is just delaying as much as you can for whatever reason.
