You aren't really going to claim that you wouldn't force sensory information stealing on someone innocent but who's still uncooperative if you thought it would be helpful, are you, Kan?
For normal crimes? Absolutely not.
If the world is ending in ten minutes and we need that information or that person dies and everybody else dies with them? Tough question. If there were other ways to get it I'd try them first, but if push came to shove...that'd probably be an invocation of the Watcher's Maxim, I think. It's an interesting thing though.
