 Crime Stoppers addresses both issues. Crime Stoppers will never ask a person for their name. If the person has information on an unsolved crime or a wanted subject, they're issued a unique code number. Then, if the information results in an arrest, the person is eligible for a cash reward of up to $2,500, and Crime Stoppers pays upon arrest, not upon conviction. People contacting Crime Stoppers are referred to as tipsters, and they are not police informants.
