Most of the projects Arnold Klein completed were pre-sentence reports for the courts. Probation officers in the special investigations unit that Arnold Klein was a member of, wrote reports after interviewing defendants and obtaining a legal and social history. Other projects completed were financial proposals to obtain funding for various projects. Probation officers also write memos to the court and the supervisors review them and sign off on them. Sometimes members of the executive staff write summary memos to the senior staff which condenses numerous documents into an easy to read summary.
