My only concern with a mood debuff is that, unless there was something like a delay on when it would kick in, it would be sorta punishing for anyone who was wanting to, say, go to the kitchen and hang out at the bar for a bit unless the debuff was relatively small, in which case it would probably just be ignored. It also might cause issues for any deputies who want to change jobs to a non-sec dept. Granted, that might just be the hazard of setting it as a job possibility like folks have with mimes and clowns. Maybe it could be something that would reduce sanity/mood over time that’s not spent in the department? No idea how that would go for coding though.
I feel like if we do unarmed combat in the dept, we’ll end up with a lot of people rolling deputy and immediately getting a job for the perk (which is against the rules, but it will be a pain to have to babysit).
