Re: OOC
Sadly, Cain and diplomacy are not exactly on close terms. If someone else thinks this could be a good idea and wishes to try, be my guest. Otherwise we can probably do this alone.
Roleplaying justification I think would be that we are, in fact, not actually guardsmen. And upholding the law and enforcing warrants sounds like the job for the city guard. Having some uniforms to back up our piece of paper could increase chances of the other side cooperating, and if not, that's where the axes come in.
