I don't agree, he's not an idiot he wouldn't provide a prescription from a practice he's worked at. I think Harrop is the person that took the photo of the prescription and posted it in some form but I doubt he he gave instructions for it to be used in this way.
This smacks of a Whatsapp group . I think it's possible Harrop is in a whatsapp group with a load of other 'activists' and he posted it there for some unrelated reason. That's where Gemma found it. I for one cannot find that prescription posted anywhere online.
Secret Whatsapp groups, Discord Servers etc, tend to explode in peoples faces at some point. So fingers crossed.
Actually I remember a tweet from Harrop ages ago, where he was talking about the closed boards on Kiwi Farms saying he was sure there was something terrible going on there, I wonder if that wasn't projection on his part.
On a positive note, if the practice were sensible they would have called in Harrop with HR present, asked him about the prescription, if he was sensible he would have told the truth, but if he lied he's now got a whole load of people (friends) with proof of that lie over him.
Smart HR will just file it away in case its needed at a later date.
