Had he takled her, there was an equal if not better chance that she could have been hurt seriously...and if that had happened we would have heard the same calls regarding police exceeding their powers from the very same people in all likelihood.
If she was not hurt, then she may have struggled to get his gun. Clearly she was trying to do every thing she could to escpe.
All of those would have been very bad outcomes and risks.
So, the officer used the least lethal way he could to stop her and there was a terrible accident. Calling him fat and lazy are clearly angry, accusative, judgemental terms that have no basis in the reality of what happened.
The accident that hurt this woman was one of her own making. She had committed two hit and runs, she was involved with drugs, and see was committing a crime by trying to escape. The officer simply tried to stop her.
Her head being split-open open was not any kind of payment for her crimes, and I do not believe any of the people involved...any of the officers looked at it, planned it, or thought of it in that manner. What it was, was a result of her bad choices...plain and simple.
Sorry she was so seriously injured...but not sorry she was stopped. She clearly would have continued in the same vein IMHO, and some innocent sooner or later was going to be hurt or killed because of her. It could easily have already happened given what she had done and the police had every right to stop her and get her off the street before that occurred.
