I think what’s troubling me is that the tribunal are judging Harrop’s response under the misapprehension that a targeted slur had been thrown at him.
But the entire tribunal doesn't rest on whether someone provoked him. He wouldn't be in this situation if he has reacted to a single provocation. He might not be in this situation if it was only one complainant.
But instead he has spent hours every day, for years, behaving badly online in public and in full view of his employers, whilst mentioning his employment as often as possible. He's doxxed an individual, and regardless of who the individual is, Harrop is not the Batman of Twitter. It's not up to him to bring who he sees as miscreants to justice.
He doesn't seem to have a firm grip on reality, tbh. Even his BBC Look North interview, he looks like he's teetering on the edge.
I can see him driving at 70mph in the third lane of the motorway, gritting his teeth in determination to stop anyone speeding, acting as his own rolling roadblock, oblivious to the chaos he is causing.
