The best evidence rule requires the original document rather than a copy when the contents of the document are at issue in the case.

Question 3

Notes are taken first, then photographs capture the scene as found, then sketches provide spatial relationships, and finally evidence is collected.

Question 4

Which of the following is an example of class evidence rather than individual evidence?

Accepted Answer

A shoe print matching a brand and size worn by millions

Class evidence narrows suspects to a group (e.g., all owners of a shoe type) but cannot identify a single individual.

Question 5

An officer responds to a burglary and finds a broken window. What should the officer do with the glass fragments found inside the building?
