Please for once let us see the entire incident instead of the "juicy" part. The story reads they have had prior contact and the woman has been know to assault officers in the past.
Last year my partner and I were dealing with a drunk one armed man who refused to stop sleeping in the parking lot of a restaurant. He put up a good fight and it took 4 of us to detain him and several times he tried to bite my partner. While at the hospital as he was getting cleaned up after fighting with us he bit me on my arm as we were fighting with him again on the gurney.
With that prior contact I now know: 1. His enormous strength despite having only one arm and 2. He will bite. With that if we encounter him again I would have no problem using a taser on him at the first sign of non compliance and I would be justified in doing so. Would the people watching us know about the prior incident, of course not and they will be up in arms (No pun intended ). But I'll be dammed if I let that dirtbag bite me or my partner again and cause me the worry about contracting a disease from him...
