I can help answer this one. I would offer you a seat in the back of my patrol car or have another officer stand with you as the investigation is on going. Keep in mind I could simply place you in investigative detention, put hand cuffs on you and place you in the back of the car. That is not consider an arrest. The threshold is low for investigative detention, its reasonable suspicion. To make an arrest probable cause needs to be met which is a higher bar to reach. And no being put in hand cuffs in the back of a car does not mean arrest by itself. Being told your under arrest, moving you away from the location of contact and time are all key factors in determining if someone is under arrest or not. But I think I have went off the rails here with more than you asked...sorry.
