“And her family?
The rule of law? Innocent until proven guilty?
Does one criminal act endorse other criminal acts - eg vigilantism, incitement to violence, stalking?”
She’s the one that’s responsible for considering her family. If she loses her job as a result of her behaviour, that’s her own fault and her own issue to deal with.
Doubtful anyone is going to go for ‘innocent until proven guilty’ when she’s on video violently abusing her horse. I’ve said before in this thread that we all know we live in a world where, rightly or wrongly, social media outrage is a fact of life. It’s reasonable to assume she knew this, especially as a teacher where online safeguarding is something she will be well aware of. Yet, she still saw fit to abuse this poor animal in public, in front of a number of witnesses.
She’s bought this on her own head.
