You can be detained for up to 72 hours in all states. It’s not an arrest, because the officer isn’t intending to bring charges against you unless there becomes a reason to do so. Then, you’ll be arrested. This allows the officer to look for reasons to see if there is a reason that you can be arrested.
Arrested is with the intention of bringing charges.

No they have to legally and formally arrest you and marandize you before they can imprison you. Then they have three days to decide whether to charge you for a crime or not.
Detained is just being delayed and held at the scene while still retaining constitutional rights. Arrest is a formal temporary loss of rights and imprisonment. I don’t care how they word it, being taken to jail and held is not just “detainment”.
This is why keeping arrest records without any convictions is BS. You can be arrested and released yet now you have a life sentence. That record of arrest haunts you for the rest of your life even though you were innocent and never even arraigned. Background checks for employment, credit score, by your new girlfriend, Etc.
When you are hauled to jail it is not a “detainment” record, it is an ARREST record. And convicted or not, for live you are automatically guilty of whatever you were arrested for. And law enforcement could care less if they destroy your life forever over nothing. Constitutional rights are designed to protect us from this very unnecessary hardship.
