I get the the /s, but if you stop someone for something trivial and then you ask them are they upset, you probably should expect something like what he got and act professionally not like a bully when you get the expected response. Instead he turned a warning into an arrest, you think that is good police work?
No, she turned a warning into an arrest.
He probably should have said “Would you be less upset if I told you I’m only going to give you a warning this time?”
That being said, he might have felt she was trying to hide something. I wonder if they found any weed or other drugs in her car? It sounds like she was a drug user.
