Admittedly, I've only read what's on CNN.com, and they portray it as she pulled up to the gate, did a 3-point turn, almost backing into an officer (easy to do in a G37 coupe), then took off and the chase began. Sure, she was crazy, but she wasn't armed, and the freakin video of the cops chasing her around the roundabout is hilarious. Why didn't the second cop block the roundabout at that point instead of chasing her and the other cop around it? Anyway, it sounds like she hit the barricade and her car was immobile before they started shooting at her, and I question why she couldn't be apprehended at that point.
If the account I have read is false, then fine. She chose the wrong place to freak out and go nuts, and these are the consequences, which I understand.
