I agree with you on that point. I admit I did not take the time to watch the video.
But there are several things in that video that made my opinion gradually turn on the police. The ankle business is the first. The second was that she was begging for her inhaler, and one officer looks through her suitcase, finds something that looks like it might be the refill portion of her inhaler, and just puts it back without a word. The third is that by the time they load her into the back of the patrol car, her breathing is so labored, you can hear it over the engine of the car. You can also hear when it finally just... stops. Not a pleasant video to sit through, overall.
