Meh. He pushed her away. She retaliated and hit him in the face. Then someone else off camera from the hallway pushed a guy into her and both he and her fell to the ground while she apparently hit the wall. A little while later Kareem still seemed upset, confronted her again and then kicked her without intent to injure.
I don't see "brutality" in the TMZ video headline, and it's not comparable to the physical violence Race Rice engaged when he literally punched out his girlfriend.
Who does this benefit the most? The NE Patriots again.
