When Cops hold you on the side of the road, you've done literally nothing wrong, and they make you prove you're innocent in roadside Court:
She calls him "stimmed-out"...what the f*ck does that mean? Then she accuses him of getting agitated because she is accusing him of sh*t he didnt do. She even doesnt argue that he passed the sobriety tests. She has decided he's a drug addict, and is going to force him to prove he's not.
Poor guy just wanted to go to his daughter's graduation.
EDIT:
I hadn't watched the last bit, f*ck this Cop makes me sick. She says he's sweaty. Hes a fat diabetic who works 15's. She says he has mood swings, they're tentatively ruining his life as he drives for work and they're hitting him with a DWI. By the end she told him she felt he was over-taking his Adderall.
So now, in the US, you can be prescribed medication, someone can say you did something weird, and Cops can accuse you of being a drug addict with your own medication. She sounds, at the end, like she just enjoyed stopping him from going to the graduation. She likes the power.
