It's always the person who finally cracks and reacts to being goaded who ends up in the shit.
You can dance along in front of someone shouting abuse and shoving your phone in their face, taking film that can later be used all over social media, and it has to be really, really bad before you get nicked for harassment.
But if the person being goaded chucks the harassers phone onto the pavements after 50 yards of this treatment, charge of criminal damage incoming.
It's a tactic used by school bullies and social disruptors alike: push someone towards a violent reaction, and then run to teacher when it finally happens. The aim all along is to get the other person into trouble.
