It seems unobtainable, but it must exist. I have long been trying to obtain a copy of police investigative procedure. It is a vital document. Without success so far, I have asked the South African Police Service, the Community Police Forum, several civil rights organisations -- and have Googled it. The Community Police Forum were the most forthcoming. After a case has been opened, they wrote, it will be "allocated to a police detective". The detective, then, will "complete the investigation". That is the sum total of it, so far. OBSERVATION: If anyone has a copy of police procedure -- just the basics -- do please get in touch. I find it hard to believe that nobody can find it.
