When he said "You're not free to go" would piss me off. If you're not FREE to go, what are you? Under arrest?
No, not initially, he was being legally detained for having committed a violation and the officer was trying to determine whether he was going to get a warning or a summons. When you get pulled over in your car for a traffic violation are you free to go before the officer completes the stop? No, you are being detained. If you try to drive away before the end of the stop, you will then find yourself arrested and cuffed. If you resist being cuffed, see what happens to ya. My guess, you'll get tased.
