I remember when the default reaction to an arrest was to fight, and that even if you chose an option other than fighting, the rules said that fighting was always more effective than any of the other reactions, and that the least violent the reaction you chose was, the least effective it would be (or something like that). Now I take a look at the rules though, and they say the default reaction to an arrest is hiding, and doesn't say anything about fighting being more effective like it used to before. So now I'm guessing the skill that affects an arrest attempt is entirely dependent on the reaction the victim chooses and strength has no influence on any arrest attempts other than when the reaction is to fight? And since hiding is the default reaction, perception is probably the main decider for most arrest attempts on NPCs? High strength used to mean you could arrest very easily but were hard to be arrested.
