The initial Crime Scene (locating, recording, and collecting); to the analysis being performed within the Crime Laboratory; and then to the Courtroom.

I’m stuck on a Law question and need an explanation.

The paper will be a step-by-step description of the selected physical evidence being handled from: The initial Crime Scene (locating, recording, and collecting); to the analysis being performed within the Crime Laboratory; and then to the Courtroom. The report should include the qualifications of both the ET/CSI and the criminalist(s) who process the item(s) at the scene and in the lab respectively. A commentary as to the expert testimony that would be given in trial regarding this evidence and its findings should be included in the Courtroom section. The physical evidence must have a complete continuity chain documented! Fictitious names, times and dates may be used. Exhibits may also be submitted with the Paper. There must be a minimum of three (3) sources used as resource for this paper. All sources utilized in the Paper must be documented by footnotes and listed in the bibliography.
