I bet she was hopped up on drugs and was a danger. I couldn’t be a cop. You get bit once, you could die of aids.
When we citizens get the same consideration, I’ll agree with that.
If she wanted to ‘wander’ out into traffic, there is much more at risk than just her.
The car/with occupants that hits her will suffer. Or that car may swerve/hit brakes to miss her, and precipitate a multi-car pileup.
So officer may be taking swift action to stop all of the above potential catastrophe.
