“What is the difference between being detained and being arrested?”
None,,, there are consensual stops where you are free to stop talking and leave. If you want to leave and are told you may not, that is an arrest according to long established USSC rulings.
It confuses many because they associate an “arrest” with being charged with a crime.
If an officer stops you, and says you may not leave, he has just arrested you no matter what new CSI term someone tries to use. Any reason he gives is the legal justification for an “arrest”.
Thanks for the clarification, my understanding was close to that.
