2. what information must be included in a crime scene sketch?
3. why is it important to include a legend (key) in a sketch?
4. what could happen in court if measurements are missing from a crime scene sketch?
5. list one advantage of a computerized sketch over a hand - drawn sketch.
6. how does proper documentation (notes, sketches, photos) help ensure credibility in court?

Explanation:

1. Circumstantial evidence can be stronger as it's often objective and can build a comprehensive picture. Finger - prints are unique to individuals, linking suspects to a crime scene.
2. In a mock trial, evidence can strengthen a case if it's well - presented and relevant, or weaken it if it's contradictory or lacks credibility.
3. A hair can have characteristics like color, texture, and root condition that can place a person at a scene even without DNA testing.
4. The two types of sketches are rough and finished. A rough sketch is made at the scene quickly with basic details, while a finished sketch is more detailed, drawn later with accurate measurements.
5. A crime scene sketch must include the location, orientation, key objects, and measurements.
6. A legend is important as it explains symbols and abbreviations used in the sketch for clarity.
7. If measurements are missing from a crime scene sketch in court, it can undermine the accuracy and credibility of the evidence.
8. One advantage of a computerized sketch is it can be easily edited, replicated, and has more accurate measurements.
9. Proper documentation helps ensure credibility in court as it provides a detailed, objective record of the crime scene.

Answer:

1. Circumstantial evidence can be objective and build a picture; fingerprints are unique.
2. Can strengthen if well - presented, weaken if contradictory.
3. Hair has characteristics that can place a person at a scene.
4. Rough (quick, basic) and finished (detailed, accurate).
5. Location, orientation, key objects, measurements.
6. To explain symbols and abbreviations.
7. Undermines accuracy and credibility.
8. Easily edited, replicated, more accurate measurements.
9. Provides a detailed, objective record.
