You certainly have a low burden of proof for when it is ok to kill a human being. Erratic behavior? You deserve death!
Regardless, there was the whole other incident in the story I linked where a man who was behaving normally was killed by a taser on film.
I do get the feeling you are looking for a loophole in every death by taser. Remember these are people, it could be your brother or father having a bad reaction to medication and because they don't listen to police they get killed unnecessarily.
I don't have any lower standards as far as when it is reasonable to kill than the next guy. However, the Taser is not a lethal weapon, much like the baton. The officer could have taken his baton out and swung it at the suspects arm. The suspect then might have lifted his arm, causing the baton to be deflected and strike the suspect in the head... killing the suspect.
The baton is not a lethal weapon when not used as such, but death can still occur. The officers in all these cases did not MEAN to kill the bad guy - if they did they would have shot him/her. Also, if one in every ten, or even one hundred, or even one thousand people were dying because of taser RELATED issues, you might have a point. But really, it's more like one in every ten thousand, and even then it's not a decent sample of the population - it's a sample of the criminal element. Millions of people have come in contact with police officers who had tasers and walked away un-tased. Each one of them could have done something to get themselves tased, but each one of them either realized they had broken the law, or decided they would take their issue where it belongs - the court room.
