In my opinion, it was a misjudgment, but think about what using Twitter is like.
Something ticked her off. She snapped a picture of it, as she had done dozens of times per day probably. She probably had no idea of the consequences. Even if you have 10,000 followers, most tweets are like that - you like something, snap a pic and share, you hate something, snap a pic and share.
I don't get the sense that she expected there to be such serious consequences. For her, tweeting might have been a reflex action. It wasn't a good decision, but let's be clear about how easy it is to lapse like that.
