Do you have CM partners? If you do, open that ESM and ESP up and take a look at the "evil" behavior scripts.
However, I think that setting a script that sets responsibility to 0 when you resist arrest might just work. Make the script and then apply it to dialogue.
On another note, is Wilson a creature or NPC? I'm guessing NPC...If that is the case, then work on another script that sets responsibility and "courage" to 0. Not sure if its courage, but something like that. The script then activates whenever the player goes into sneak mode, that way he doesn't attack that Bandit Ringleader you wanted to get a sneak attack on.
