None of us was there. If she was belligerent drunk, how could she reliably remember everything that happened ? More likely story is she refused orders to calm down, assaulted CO's and got tazed before being restrained. That would be a perfectly reasonable thing to do.
None of us was there, as you said. I do not take it as "more likely" that the victim earned three tazings. I also don't believe that effective policework would ever require tazing a drunk person three times.
And as has been said elsewhere, she was restrained all throughout.
