I don't think lawful is the alignment you're looking for, but as I understand it, bounty hunters need the support of a greater network (either in terms of firepower, specialists or information) in order to be successful. That about right?
Not a criticism, but personally I don't feel great about RP's where everyone holds each other at gunpoint. Of course, this is up to what kind of characters are created, so I think I'll hold back a bit until I see others their sheets. I hope you understand.
