reporting it doesn’t necessarily mean the police do anything, it can just go on record in case of future incidents (either him in his car or him going round to Ton’s house).
I had a neighbour threaten to burn the house down in the night. I reported it, coppers said they didn’t have previous complaints about him, we agreed that no action was needed (as it would only have caused more aggro) but it was now on record in case I or anyone else had problems with the same bloke.
