He knows he’s in the wrong, is my point.
True but sadly no longer the point for him, and admission of guilt at this point might bring with it further charges now this has been legally escalated. So of course he’s going to take advantage of the lack of evidence and the polices intransigent attitude.
As for the actual incident, I don’t think there’s anything to be gained by telling you to turn the other cheek. If someone comes up to you with unprompted abuse and threats there’s no real way to know how you will respond until you’re in the actual situation, so who are any of us to pass comment on your behaviour.
But in future I’d not tell them they’re “being recorded” or “on camera” its a red rag to a bull phrase (ref: half of YouTube) and you’ve no duty to inform them IMO, just allow dickhead to incriminate themselves, that’s the whole point of passive recording…
What I will say is that you shouldn’t let it take up a second more of your time and energy than it has to, the investigation is closed. I would lodge your complaint with the IPCC, let it run its course and then put the whole thing behind you.
There are things to be grateful in all of this, he didn’t follow through and smash your teeth in, and karma is sort of served by him probably having spent more with a solicitor than it would have cost to replace the property he damaged, funnily enough money he can’t now spend on better gates to secure his flock. Plus he’s probably now on the local plods radar for being an aggressive arse to strangers…
Ultimately you “win” more in this situation if you don’t let it affect you unduly. Sometimes easier said than done…
