Regarding the travellers sites, I have spoken with my SNT sergeants none of the locations on the list stick out as particularly worse or better than the others from a crime and disorder point of view.
We only have the one site which is relatively small and remotely located at Beausale and we have no evidence to suggest that this has had an impact on crime levels. We have good relations with the people on the site who are always friendly and polite. I can't speak for anywhere elsedisorder point of view.
