Neighbour follow up!

Happy New Year everyone!

Today, my neighbour has again started shooting his air rifle, the police have been out again, after we reported him again. We've had more than 15 dead birds now, pigeons, magpies.

His wife apparently told them last time there is no air rifle and the police have said there's nothing more they can do unless I film him using it. Without going into his garden I can't get footage of him with it, he's surrounded by conifers. 

I'm at my wits end with it all, and dreading the spring again.  

My partner won't let me go round to speak to him, as she says it won't help. But I don't know what else I can do.

The police aren't interested.

Has anyone else had to deal with a situation like this??

Thanks
