The “error in judgment” was in allowing herself to be caught on video. Like people who beat their kids, she’s taking her frustration at failing to get what she wants out on a being that can’t fully comprehend what is demanded of it or why it should comply. Shitty, bratty person.
What is the actual point of that? She's trying to make it jump around?
As for "error of judgement" she looks calm as fuck and that's not the first time she's done that
