And yes, an unlawful police faction seems to fit the PSG well. I mean, we have three Rheinland criminal groups that want revolution and chaos. I think Rheinland needs a faction that promotes order.
The Bundschuh has a very difficult position on Discovery, because ALL of the other Rheinland Unlawfuls took over the role of revolutionaries, that was originally intended for the Bundschuh. In Vanilla, the Hessians were Pirates, the Unioners and LWB terrorists (against Republican and Synth Foods respectively). Now they are all political and render the Bundschuh superfluous.
I think the approach of a moderate, unlawful "Police" faction is the best way to integrate the Bundschuh as a unique and influential force in Rheinland, without impeding the other groups' Roleplays as revolutionaries.
