Just one of my passing thoughts from today. Say a member of the Temple committed a crime there in the period before the incident: would the Guyanese police have dealt with them, or did they have some arrangement that let the Temple do their own thing in terms of policing their people?
/u/cordis_melum has previously answered What did the Guyanese gov't do about Jonestown and the events that transpired there? What impact did it have on Guyana? but others might have a different point of view.
EDIT: /u/xaviira has previously answered How were relations between the United States and Guyana affected by the events at Jonestown?
