Anyone saying “use the taser” may not have seen one deployed, or didn’t watch the video.
A knife can get you close range (like how she slashed him partially out the door when he was in knocking range) and a taser deployed that close would be relatively ineffective/inaccurate.
If he would’ve knocked and dropped 10 feet back (nearly impossible in that corridor) a taser would’ve been ok, but he was a foot away and she opened the door pretty quickly.
Sad all around. It seems like the likeliest outcome of this situation was that someone was going to lose their life. RIP to her, if she had demons, at least she’s not living with that reality anymore
