The voice of reason, I think, would say this...
1. What was done to her was WAY OUT OF LINE, and charges are appropriate.
2. Rand Paul should have immediately condemned it, but at least he (through his people) did eventually do so.
3. The shoulder versus head, stomp versus heavy push is important, because it is important to give an ACCURATE description of the incident, so as to avoid INFLAMMATORY EMBELLISHMENT of what happened, which would be done solely for political reasons.
4. After reviewing the video many times, I feel that the SHOULDER was what was shoved/pushed, and it was done so much harder then would ever be needed for "restraint". The head seems to have been struck on the concrete below as a result of the motion. She did sustain a head injury, but based on my viewing of the tape, I would suspect it was secondary to the push of the shoulder causing her head to strike the concrete.
5. Semantics I am usually not in favor of debating, but I think when accuracy is important, here to avoid politically motivated embellishment, then one must try to be accurate.
