Yep
the “she” being refereed to is the officer. Officer Wakana Okuma is a female.
I just watched the video, and the girl does point the drill at the cops several times like she is aiming a gun. I still think they should be able recognize a drill from a gun, but it does look like the girl was trying to get a reaction from the cops...
On a separate note, I think I used to live in the unit this girl was in front of. At least I know I lived in a unit on that exact corner about 15 years ago... Those are not apartments, but are 4-plexes.
