My advice to you would be to work within the law & Just keep on monitoring and gathering data on the Prize Turnip for the big day,and remember the pen is mightier than the sword.
Ask the police to come and look at your camera/s in situ so they can advise you on the best way they should be positioned to protect your property. That should shut him up,.
Bigger the man who Weals the pen rather than the sword, or so I’m told ... I adjusted it, got the copper to check it on my phone, to which he said “ oh yes that’s fine” when he had gone I put it back to it’s original position...x
