Should a Bounty Hunter only have good combat skills, or should they be allowed to develop some Deviant skills to help them track down the target they are looking for?
Disguises, Forged docs, Lock picking, etc could be some useful skills to have when trying to track down a target who is hiding or is in disguise.
Let's say you are hired to bring back someone. You go to the town where they are known to be hiding, but you do not want to just waltz into town. You don a disguise and when someone asks you to show your papers about who you are the papers look legit. You're not Lothgar the Bounty Hunter, you're Billy the Traveling Tradesman looking for business in town. That way your target doesn't hear some gossip that there's a known bounty hunter in town. When you track them down to where they are living you can pick the lock to their house and check for traps, and hopefully get them while they sleep.
To get these skills you would need some kind of protection from the law to get these skills leveled up. Sure you should be punished or fined if you break a law that doesn't have anything to do with your target, but when collecting the data needed to find them would you allow them some leniency in breaking some laws?
