I know you don't want answers but I feel uncomfortable with the use of the word community to describe a group of people who share certain charecteristics- whether it be race, sexuality, religion, gender, ageamd why anyone be responsible for individuals who break the law. Most sex offenders are men but I don't know who from the male community should be responsible for helping. Who represents the white community in a town- let's say Rochdale for example.
Anyone who has information should help, and if there are barriers that stop people cooperating then those need to be broken down somehow- which may take time
