The woman was leaving. The cop prevented her from leaving. She had committed no crime and he did not need to get her ID for some fake reason.
He’ll soon be out of a job and she’ll soon be suing the cops, the city, and the McDonald’s.
She was leaving the scene of a criminal trespass & disorderly conduct complaint, according to management who called the police and as retold by this YouTube lawyer.
Not sticking up for the cops, but asking for an ID is a lawful order. However, that does not mean you beat some woman in the face as punishment. This guy was a Police Sargeant and should have known better.
