Thing is, torture's horrifically ineffective for extracting useful information and doubly unnecessary when you have mind-reading powers. Rules or no, I don't see Kait stinting from using those abilities if it would ferret out the specter of crime.We know that, and sane people know that, but would a person who learned everything they know about law enforcement and justice from TV shows know that? Kait may see roughing up perps in an interrogation as a necessary part of the law enforcement process. And while she may be able to establish guilt to her own satisfaction by plucking the information out of their brains, she'd probably still want a written confession. Pressing their minds into confessing A. isn't a proper confession, and B. violates the 'don't run their brains' rule.
I would also imagine that they were born in different parts of England.
