This is on edutwitter but I know that some on this section are interested in this sort of thing so thought I would share it here.
A (reasonably well known and quite strident) teacher has quite a few detractors. One of them reported him to the police for harassment, the teacher was emailed and warned about their conduct.
"I emailed the PC with questions about what I'd done. I got no response. I sent a Subject Access Request and was told that the only information that could be released to me was the emails that I'd already been sent. While I wasn't expecting details of the complainant's accusations, this made no sense if the complaints had been investigated, that there would be no record of what I'd tweeted, no record of the phone call and no record of the warning in the email (the email had literally said "It will also be recorded that you have been warned about this behaviour").
With regard to 2) I went through all the guidance the police have for investigating harassment. Most seemed to imply the police shouldn't give "words of advice" or "warnings". I put in a Freedom of Information request to the relevant police force about their policies and procedures and they could find nothing about giving "words of advice"
The teacher got in contact with Harry Miller and the Free Speech Union who supported him with his dealings with the police who seem to have backed down.
