What is stated by Locard’s Exchange Principle? O The transfer, loss, or contamination of evidence can occur if an area is left unsecured.

According to Locard’s Exchange Principle, what do exchanged materials indicate? O That the two objects were in contact

What is the basic purpose of note taking? O To document facts

What are characteristics of effective notes? O They are… O Complete O Accurate O Specific O Factual O Clear O Well-organized O Legible

What are techniques for effective note-taking? O Only record facts, NEVER opinions O Record facts accurately O Be as specific as possible O Write legibly and clearly O Keep the pages for each case together and record the page and case numbers on each paper

How do you correct an error in your notes? O Cross it out with a single line and initial it

Are notes allowed/admissible in court? O Yes

When can notes be used during testimony? O Only after asking for permission to use them. O They should then only be used to refresh your memory. They should not be read from.
