Matthew Broaddale, village bike
I mean, setting aside the feasibility of stopping Custer, he's clearly and explicitly AWOL, right? He doesn't have any authority beyond his force of arms, and Manning was supposed to arrest him, as far as I remember. As a duly appointed lawman, I would imagine that Logan, myself and probably even Steinhof, if he's acting as a part of Manning's detachment, have the legal authority, and perhaps even legal duty, to apprehend this... I mean, he's pretty much a warlord, right? A rogue asset occupying a foreign city. Or if Deadwood counts as Union territory, illegally quartering themselves in private citizens businesses/homes.
I guess I'm saying that if Matt wasn't a pacifist, I could see it happening.
OH, yeah. The fire is probably more of a problem, but Matt's kindof spacey. Plus i wouldn't want to step on the Iron Horse Whisperer's attempts.
