This where your gut comes into play especially with traffic stops. Sometimes if the cop seems cool I'll give it up and actually confess that I might have broken a traffic law. This has only backfired on me once in Rockford. OTOH I had a cop try this exact technique on me in Indiana when there was a bad crash and I was looking for a detour. I wont go into details but that's traffic BS and his games got turned on him badly.
If I were guilty or accused of possibly being guilty of something more serious then a moving violation I'm not saying a word. Some of this depends on the actual officer involved, I did own a pawnshop on the Westside and frequently dealt with the pawnshop detail. A couple of the detectives on the detail were very cool but one was one of those "I assume you are guilty of something" types.
