The site residents and/or Police were probably more concerned that the rightful owners of various vehicles and items of property might spot them in the pictures from the drone. Knowing how the Police will do anything to avoid confronting such people about retrieval of property, both groups were probably only too happy to work together to prevent the drone operator from getting the pictures.

Surrey Police said he was arrested following complaints his behaviour was "disrespectful and intrusive".
I hope neither the Police or the site residents would be hypocritical enough to view distressing images from Iraq, West Africa or anywhere else in the world.
