So you agree that public donations that are given to treat and feed animals should be spent on prosecutions?Not sure if I agree with that.
It's a private charity, funded by volunteers, as stupid as some of their prosecutions are, it is their right to prosecute. You can't ask the government to stop a private charity from prosecuting.
Their TV advert should read .. Please donate £3 a month so that we can carry on prosecuting the old and the vulnerable.
