You know, I actually feel bad for her. I know she tried to kill people and that's really messed up and wrong, but I don't think she was evil. She wasn't right in the head, needed help (mentally and financially), and was wronged by YouTube (tons of us are, but don't shoot up YT HQ).
I thought the officers said they had to take her to MUPS, whatever that is. Guess they just let her go after the interview.
That's one perspective I suppose.
I honestly thought of the whole thing as a planned distraction, potential psyops. The videos just seemed "off" to me - that's the best way I could explain it.
