Thanks for the answer, and the movement! 

Also, my incompetence in making a board URL has been fixed: the link above now works.

Again, thanks for the help.

"Do What's Right Here...": Zack excels at convincing people to do the right thing. He gains a +3 bonus to Rapport checks when convincing criminals or suspects to do what is right, such as revealing evidence (on themselves or others), confessing to a crime, or turning themselves in. Restriction: This Stunt doesn't work on creatures with no conscience (including many nonhuman monsters) or no notion of right or wrong (such as psychopaths.)

Notes: +2 is the normal bonus for Stunts, which work in restricted conditions (such as hiding in the crowd). This Stunt is even more restricted than usual, being only useful against things that understand and accept what right and wrong is, so I increased the bonus to +3.

If this is inapplicable, then I'll keep it at +2.

"Give It Up!": Zack's devotion to seeing justice done is imposing. For the purposes of the Threat trapping (Dresden RPG, "Your Story", 133) he can use his Presence instead of Intimidation.

Notes: This second is a pretty stock usage of a Stunt, at least according to "Your Story", 147. I think it passes muster pretty easily.

Thanks for all the comments, UmbraLux and computerking.

i'm playing a cop, Zack Donovan. These are two Stunts I'd like to use. I'm new to Dresden and could use some feedback to help tune up the mechanics.

"Freeze, Police!": Zack's devotion to justice is intimidating. So long as he's confronting a real or suspected wrongdoer, he can use his Presence instead of Intimidation to Threaten a suspect (Dresden, "Your Story", 133). Threaten is an attack that deals Mental stress.

"Do What's Right Here...": Zack has supreme confidence in his authority, both legal and moral. Even in instances where he lacks legal authority, his desire to see justice done gives him the confidence to talk wrongdoers and suspects into doing what's right. Using Presence, he can talk criminals (or suspected criminals) into surrendering, convince them to confess (or reveal other information), and otherwise listen to him, even when its not in their best interests.

These two Stunts both play into his identity as a police officer. They provide explicit benefits in pursuit of his job, or even in pursuit of justice (such as pursuing a creature that would otherwise be outside of his jurisdiction).
