It's hard to tell exactly what happens in the video because it's blurred (and maybe the settings on my monitor don't help - not sure). You see him step up to her and she goes backwards towards the car, but you can't (or at least I couldn't) see any part of him extending, like in a push, out towards her. He's wearing black and it's a night, so like I said, it could be my settings, along with that, preventing me from seeing a shove. The more damning part of the video for me is after she sits down in the car and his hand goes in and out of the car quickly. It's possible he was tossing something in the car, but to me, the movement looked more like a quick slap.
