Being legally allowed to stop someone doesn't mean you have to treat them like trash.
I got stopped while entering the US, they asked me to follow them in some kind of room, I did, they asked me for my passport, I gave it to them, they then put the passport on a table and went chatting on the other side of the room, a few minute later a woman came in and took the passport while no one was paying attention. 5 min later one of the chatting officer noticed the passport was missing and tried to make me confess I took it back from the table and hid it, he was very obviously trying to escalate the situation... The woman came back after a while and the threatening officer tried to pass his whole act as a joke. I lost 2 hours because these people were less organised than an elementary school kid and treated me like a criminal for no reason.
