The problem I have with this sort of thing is that I can see nothing but a few blobs and am aware that all sorts of things can be introduced into an image, unintentionally, by applying filters and 'enhancing' images. There is also the point that the human brain tends to try to interpret patterns to be something we recognise and are familiar with, such as faces. If you go looking for faces in random patterns you can usually find them. Also, I would ask, how tall would someone have to be to be able to fire a rifle through that opening?
Fair enough to look at things like this and to examine things with fresh eyes but to declare something like this as proof of the identity of a pergola shooter isn't accurate I would say.
