The footage tends to come to our attention partly by other people who have seen it reporting it. That is particularly common with juvenile offenders of school age, where peers in school will see their friends publicising themselves on one of these sites and are appalled by it, and so they report it. We do have officers who tend to trawl the internet looking for evidence of cruelty, particularly the more organised crime, such as large-scale puppy trading or dog fighting. I cannot recall a time when we have had to go to one of the internet company providers. I do not know what sort of reaction we would get. I am not aware of it being done.
