When the cuffs go on, you ARE being detained at that time. Usually for officer safety, (or in some cases the safety of the subject) but can be used to safeguard evidence during a stop prior to arrest or with charges pending. If the officer decides not to pursue further investigation or charges, they will release the individual(s) at that time. Most LEO's seldom cuff someone outside of a warrant hold. Occasionally you will get a hit on someone's name as coming back with warrants or wants against them, the cuffs may go on at that time until it becomes clear that the individual is not the subject of the want or warrant. Otherwise, they get transported to the lockup still in cuffs.. Just my prior experience..
