The part I'm not sure about is whether or not the officer owes you an explanation for the stop or if so at what point. I'll have to research this more.
This only applies if you raise a 4th amendment challenge later. The officer owes you no explanations and most will not offer them. PC can also be developed over time. An officer may simply strike up a friendly conversation. Instead of walking away, you feel obligated to talk or ask silly questions like "am I being detained". You think he's being pleasant when in reality he is looking for conformation of his suspicions.
A stop or "seizure" requires a show of force by the officer. You must, in the eyes of the court, be in a position that a reasonable person would not feel as though they could leave. Example, lights in your rear view mirror, a command from an officer to stop, two cops approach your vehicle with one on either side, etc. This is very broadly defined and is held up to rather difficult standards by the courts. Most people would not walk away from ANY contact an officer makes. But, without a show of force, most courts will assume any information you divulge was consensual.
There was a 4th Amendment claim recently shot down in District Court where the defendant claimed the officer was too nice. He claimed that had the officer been more aggressive he would not have answered the officers questions.
