She was holding the knife to her own neck. The only person she was threatening was herself.
looking at the video. She was close enough that she became a danger to the officers once she turned the corner of the bed. At the point she can cross the distance and injure someone other than herself.
Officers also talked about non-lethal (still not sure why those werent used first),and were talking to her the whole time in Spanish. The officers did all they could it felt like, unless you feel someone getting stabbed and possibly killed is worth her living.
The goal should be no lose of life or injury on either side, and I dont think that could have happened here.
