Perhaps approve is the wrong word, but do the police appreciate the work of these groups? Would they rather they didn't act as decoys or 'stingers'? I'm asking as I saw a live on Facebook where a hunter group went to the house of a man who had been online grooming a young teen. The police came, man was taken away. The main hunter guy said something along the lines of "the police work very well with us" and it made me wonder do the police think these hunters are doing a good job?
