Abigail Mitchell - whether she really killed a murderer or not.
Tommy Brown and Adrian Carsini have been mentioned a lot when it comes to this.
Marshall Cahill, especially after the trick he played on him, which he probably found very embarrassing.
Paul Galesco - maybe that one is reaching, but that trick seemed to embarrass him a little too.
Grace Wheeler, Viveca Scott, Nora Chandler were all "celebrity crushes" of his in one way or another.
I wonder how he felt after he had to arrest a federal agent, namely Nelson Brenner, in Identity Crisis. I've often wondered what Nelson's boss, the director, thought about that. I suppose once you step over the line and become a criminal, it doesn't matter who you are.4
