I have not read the entire thread, but I'll throw my opinion out there anyway.
It is tragic and terrible and heartbreaking that a 20 year old woman has essentially died. Wouldn't it be tragic if she run into traffic and been killed by a speeding vehicle? Wouldn't it have been tragic if she had died before her arrest due to extreme intoxication, or the adverse effects of alcohol mixed with pain meds? Wouldn't it have been tragic if she had fallen while headlong while running form the police while handcuffed and become brain dead?
Yes. But that's not what happened. She was under arrest, she had been transported for processing. She was caught and she was going to jail. She didn't want to go to jail, so she tried to run away, never mind the fact that this presented a huge risk to her own safety. No, she might not have been thinking clearly, but her own actions led to her lack of clear thinking.
The police officer tasered her. While she was running away from his custody, and endangering her own life. he made a choice, one choice, to try to counteract the potential side effects of the many, many bad choices she had made up until that point.
That's how I see it. It didn't work out like the officer planned, it didn't work out like the criminal planned. Sad all the way around, but life goes on. Don't want to get Tasered? Don't run from the cops.
That's my take on it.
