Accepted Answer

Excluding reporters, government officials, curiosity seekers, and superior police officers who are not directly involved in an investigation ensures that a crime scene is properly protected from contamination and interference. This enables law enforcement officials to search the scene thoroughly and collect evidence without distractions or outside influence.

Question 3

The crime scene provides the major opportunity to

Accepted Answer

The primary purpose of a crime scene is to locate and collect physical evidence that can be used to understand the crime and potentially identify the perpetrator.

Question 4

Accepted Answer

In 1984, the United States Supreme Court case Michigan v. Clifford reversed a decision based on evidence obtained by investigators who entered the scene of a suspected arson five hours after the blaze had been extinguished, emphasizing the need for a warrant in such situations.

Question 5

In Katz v. United States, the United States Supreme Court created the presumption that

Accepted Answer

The Supreme Court in Katz v. United States established that searches conducted without a warrant are generally presumed to be unreasonable, emphasizing the need for judicial oversight through warrants.

Question 6

The clothing and body of the victim, as well as the items under the control of the suspect, are considered to be

Accepted Answer

Clothing and body of the victim, as well as the items under the control of the suspect, can potentially provide physical evidence that can aid in a criminal investigation. Such evidence can include DNA, fibers, fingerprints, and other trace evidence that can be analyzed in a crime laboratory and presented in a court of law. Therefore, these items are not useless, inadmissible or of no practical use to the investigation.

Question 7

According to the text, before any physical evidence can be collected and transported, it must first be

Accepted Answer

The answer of According to the text, before any physical...

Question 8

The major methods of recording the situation, conditions, and physical evidence discovered at the crime scene include

Accepted Answer

Notes, photographs, and sketches are the three major methods used to record the situation, conditions, and physical evidence discovered at a crime scene. While crime laboratory reports and investigator's reports may also be useful, they are not considered major methods of recording the crime scene. Therefore, the best choice is B.

Question 9

A relatively crude, freehand representation of all essential information and measurements made at the crime scene is known as a

Accepted Answer

A rough sketch is a relatively crude, freehand representation of all essential information and measurements made at the crime scene. The other choices are not accurate descriptions of a rough sketch.

Question 10

When the distances in it are precise and proportional, with lines drawn by a skilled drafter, a finished sketch is known as a

Accepted Answer

A scale drawing is a type of technical drawing that shows objects at their true size, in proportion to each other. It typically uses a scale such as 1:100 or 1:50, where one unit on the drawing represents 100 or 50 units in real life. This makes it possible to accurately represent objects and spaces in a clear and precise manner.

Question 11

After each item of physical evidence has been properly recorded, it must then be

Accepted Answer

Physical evidence must be collected separately and preserved for examination in both the laboratory and eventually in court to maintain its integrity and ensure it can be properly analyzed and presented as evidence.

Question 12

Biological specimens, particularly blood and semen stains, are best preserved by permitting the specimens to dry at

Accepted Answer

Biological specimens, particularly blood and semen stains, are best preserved by permitting the specimens to dry at room temperature, away from direct sunlight. This prevents the growth of bacteria and allows easy collection and analysis of the specimen. High temperatures can cause the specimen to coagulate or degrade, while storing the specimens below room temperature can cause moisture to develop, which can also degrade the sample.

Question 13

Comparison specimens of known origin are called

Accepted Answer

Comparison specimens of known origin are called exemplars. This term specifically refers to samples that are used for comparison and reference purposes in scientific analysis or forensics. Variables and control variables refer to factors that are being manipulated or monitored in an experiment, while samples and examples are more general terms that could refer to any type of specimen.

Question 14

According to the authors, the techniques for discovering and gathering trace evidence are

Accepted Answer

Adhesion to tape, shaking or sweeping, and vacuuming are common techniques for gathering trace evidence such as hairs, fibers, and microscopic particles. Raking is not typically used as it may disturb or move the evidence, while dusting may only be effective for larger particles.

Question 15

According to NYPD Detective Nicholas Petraco, the most important and versatile instrument available to the criminalist for the study of trace evidential material is the

Accepted Answer

The microscope, especially the polarized microscope, is crucial for examining trace evidence due to its ability to provide detailed images and analyze the properties of small samples.

Question 16

According to the authors, the initial response to the crime scene should be to regard it as the only chance to recognize, record, and collect physical evidence.

Accepted Answer

This statement is true according to the authors who emphasize the importance of recognizing, recording, and collecting physical evidence at the crime scene as it may be the only chance to do so.

Question 17

Delayed or late attempts to enter a crime scene are legal if the permission of the owner of the premises is obtained in writing.

Accepted Answer

Delayed or late attempts to enter a crime scene can be legal if the permission of the owner of the premises is obtained in writing. This is typically done in cases where the crime scene may have been disturbed or altered due to emergency responders, but evidence may still be present. However, it is important to note that there may be limitations and restrictions to such delayed entries and proper protocols must be followed.

Question 18

Scale drawings are not beneficial in court because exact distances are not demonstrated.

Accepted Answer

Scale drawings are beneficial in court as they provide a proportional representation of the object or site in question, making it easier for judges, juries, and legal professionals to visualize the scene. While exact distances may not be explicitly shown, measurements can be provided in the legend or through annotations on the drawing, and professional surveyors can use the scale to calculate precise distances if necessary.

Question 19

According to the authors, it is not necessary to account for evidence continuously from the time of its discovery until it is presented in court.

Accepted Answer

The authors emphasize the importance of maintaining a continuous chain of custody for evidence, which means accounting for the evidence continuously from the time of its discovery until it is presented in court to ensure its integrity and authenticity.

Question 20

According to the authors, most criminal investigators do not collect comparison samples of adequate size or quantity.

Accepted Answer

The authors state that "most criminal investigators do not collect comparison samples of adequate size or quantity" (implying that they collect samples, but not of sufficient size or quantity).
