I don't see anything wrong with officer using taser on that woman.
Did you see body language of suspect once she got out of her car? Leaning forward, arguing, being difficult.. What could have happened? She could have pushed the officer into the traffic, or worse..
How did this happen?
Officer used forceful tone of voice, which triggered defensive responses in that person.. Cops do that routinely..
For example, last week, after a fight, cops let everyone go, including myself.. However, they weren't happy with that, so one of them decided to poke me with some questions.. I already hated the guy for reading me a moral.. So my response was to answer and raise my head so that my bright light is into his eyes.. He goes somewhere and comes back with even more questions.. Provoking me to loose it.. Bad guy, if we make him loose it, he can have him.. All I did was answer and keep my head down, and was on my way... That's submitting, and that's what they looking for.. Some people have problems with submitting, and would rather do stupid things...
At times like this your macho sh!t kicks in, you got the law (which by the way you don't know nothing about) as your guide towards whatever.. You think you're right.. Officer is yelling at you, he stopped you, even the mare fact that he is talking to you feels bad..
The only thing that can be done then is lean back, and speak like you're innocent.. Calm.. When you are calm, he is calm too..
