Question 1

As part of crime analysts' pattern analysis process for micro-time hot spots, they have to determine all of the following criteria except:

Accepted Answer

B

Question 2

Which is the emergence of several closely related crimes within a few minutes' travel distance from one another?

Accepted Answer

The emergence of several closely related crimes within a few minutes' travel distance from one another is called a micro-time hot spot. This term refers to a small area where criminal activities occur frequently and are closely related. It is different from spatial analysis, which involves the study of the relationship between crime and its location. Hot prey refers to the potential victims that are likely to be targeted by criminals, while Tempogram is a visual representation of the temporal distribution of crime.

Question 3

Patterns are often found by linking MO factors alone.

Accepted Answer

MO theory can be useful for predicting and explaining properties and reactivity of molecules, but it cannot solely determine patterns. Other factors such as steric effects, electronic effects, and thermodynamics also play a role in determining the behavior of molecules.

Question 4

The most appropriate time series method for examining a pattern of ten robberies is:

Accepted Answer

Examining the exact time of day/day of week when the robberies occurred would be the most appropriate time series method. This would allow for identification of any patterns or trends in terms of when the robberies tend to happen, which could inform strategies for prevention or increased surveillance during those times.

Question 5

When describing the temporal nature of patterns, which are not appropriate?

Accepted Answer

Mean and standard deviation are statistical measures used to describe the central tendency and variability of a dataset, respectively, and do not directly describe the temporal nature of patterns, which is related to time.

Question 6

Crime pattern bulletins include a title, summary, list of cases, map, and time series analysis.

Accepted Answer

Crime pattern bulletins typically include a title that identifies the focus of the bulletin, a summary that provides an overview of the problem, a list of cases that detail the specific incidents or crimes, a map that shows the location of those incidents or crimes, and a time series analysis that highlights trends in the data.

Question 7

Which chart would be most appropriate to show robberies committed by a suspect to support a drug habit that may occur closer together in time than other robberies?

Accepted Answer

A chart displaying intervals between events would be most appropriate in showing robberies committed by a suspect to support a drug habit that may occur closer together in time than other robberies. This type of chart can show the frequency and duration of the robberies, giving insight into possible patterns or trends.

Question 8

There are several types of tactical bulletins, including pattern bulletins, persons' bulletins, and property bulletins.

Accepted Answer

This statement is true. Tactical bulletins are used in law enforcement to disseminate important information quickly and efficiently. Pattern bulletins alert law enforcement officers to specific crime patterns or modus operandi of suspects. Persons' bulletins provide information about wanted or missing individuals. Property bulletins provide information about stolen property or other items of interest to law enforcement.

Question 9

Which type of analysis would be most appropriate in examining the exact time of occurrence in a robbery or a sexual assault?

Accepted Answer

The answer of Which type of analysis would be most...

Question 10

Which information would not be found in a pattern bulletin?

Accepted Answer

The answer of Which information would not be found in...

Question 11

Which is used to disseminate crime pattern and other tactical information to officers, detectives, and citizens?

Accepted Answer

Pattern Bulletins are typically used to disseminate information about crime patterns and other tactical information to officers, detectives, and citizens. Tempogram and cross-tabulation are analytical tools used to analyze crime data, while dissemination refers to the act of spreading or sharing information.

Question 12

When describing suspect and vehicle patterns and conflicting information arises, the analyst has to be sure of what?

Accepted Answer

Conflicting information should be noted as it can provide a broader understanding of the situation or indicate the need for further investigation. Ignoring or discarding such information could lead to incomplete or inaccurate analysis.

Question 13

Components of a crime pattern bulletin include all of the following except:

Accepted Answer

The names of the officers who took the reports are not typically included in a crime pattern bulletin. However, a matrix of key variables, a map, and a time series chart are all common components.

Question 14

As an analyst, describing the MO of a pattern should focus on:

Accepted Answer

When describing the MO (Modus Operandi) of a pattern, the focus should be on the characteristics that are shared by all cases and distinguish the pattern from other patterns. It is important to avoid drawing concrete and confident conclusions without sufficient evidence, and analysts do look at patterns to describe MO. Therefore, option B is the best choice.

Question 15

The most appropriate method for examining five car burglaries is:

Accepted Answer

The answer of The most appropriate method for examining five...

Question 16

In which type of analysis are single symbol maps used by enable analysts to examine the geographic nature of the crimes and begin to identify patterns?

Accepted Answer

Single symbol maps are commonly used in spatial analysis to visualize the distribution and clustering of crime incidents. This helps analysts identify geographic patterns and hotspots which can inform resource allocation and strategy development.

Question 17

Weighted time span computes

Accepted Answer

Weighted time span computes each hour within a time span as a proportion of that time span.

Question 18

Police use the information in tactical crime analysis bulletins to raise citizen awareness, to try to catch offenders, to investigate crimes further, to clear old cases, and to prevent future crimes.

Accepted Answer

Police use tactical crime analysis bulletins for a variety of purposes, including those listed in the statement.

Question 19

It is important to describe every case's suspect and vehicle description in the final pattern bulletin.

Accepted Answer

The final pattern bulletin should focus on summarizing the key details that link the cases together, rather than describing every suspect and vehicle description in detail. This helps in identifying the pattern and critical elements of the crimes.

Question 20

Which would show a count of crime by both time of day and time of week?

Accepted Answer

Cross-tabulation is the process of comparing two or more variables by creating a cross-tabulation table, which shows the distribution and frequency of each variable. In this case, the two variables are time of day and time of week, and the resulting table would show the count of crime incidents for each combination of these two variables.
