1) yes, cuffed and taken to the station
2)no. Very clearly stated that I wasn't under arrest, "You're not under arrest, we just want to talk to you."
3)yes. I matched the description of a guy that someone reported who was tagging.
4)no, I was being "detained." I know that because I asked if I told them I was going to be late for work. I was giving them an attitude, which was why I was in cuffs, and asked why I was being cuffed. His words IIRC were "I don't care for your lip, so were going to cuff you for your safety and ours."
I was walking out of the donut shop, coffee and breakfast in hand when they came through the parking lot as I was walking to my truck. I was just about in my truck when the came racing up on me and jumped out(2 guys in the car). It startled me so I started off lippy with them. That set the tone for the encounter, and I honestly think the only reason I was taken to the station was because I was being very aggressive with them. But it was made very clear to me I wasn't being arrested. I was still living with my folks at the time and said to call them for proof. This was before cell phones were as prominent as they are today. I had a pager at the time(I think I was all of 18 or 19). So, they brought me down to the station, searched my truck where they stopped me for rattle cans, and called home to see if I was lying. After was all said and done, I got an apology, and was brought back to my truck. He told me on the way back, "I'm sorry for the trouble, here is my card if your boss tries to give you crap for being late. Have him call the station if you need to."
