In fact, we may just find out that the Lt. had just come from witnessing the fresh cigarette burns on a 12 year old's body. Puts a pretty different complexion on it, yes?
NO, it does not. The minimum amount of force necessary. NOT the minimum amount of force, depending on the allegation. The minimum amount of force necessary to effect the arrest. I watched the video, Granny SITTING IN THE POLICE STATION, officer reaches out, granny pulls her arm back. You tell me, Is this officer, big officer, afraid of an elderly granny, afraid that he thinks he is in physical danger to the degree that he must resort to a taser? If he was afraid of harm from that woman, he (the officer) needs to find a new line of work, maybe at a flower nursery.
Tasers are good in some circumstances, this was not one. Tasers used as a compliance tool to herd people like cattle is not a good thing. Once that becomes common practice, it will be verboten to speak ill about it, or you will be labled a cop basher.
