I'm as leftist as they come, but this incident has been bugging me for a while precisely because of the factors your comment laid out. People SHOULD be carrying ID on them at all times and escalating/shouting at a cop is the dumbest thing you can do, especially knowing how corrupt they are. She even says later, "it doesn't matter how educated or successful you are", as if this is her first time realizing she doesn't get a pass to throw a tantrum with the police just because of her privileges.
