You are the crime analyst in a small to medium city. Your department is still using the pushpin type system of crime mapping. This is a very rudimentary style of mapping. In fact, one may have more than one crime in the same block on one day.

- The crime plotting example shows the crimes.
- When it asks for a cluster, you would look for a certain crime and decide if there is a cluster and in what section of the town it would be located.
- When it pertains to suggestions to the chief for shifts, you do this by time.
- The time plotting example shows the same crimes by shift.
Download Weekend Crime Reports. You are to map each crime reported over the weekend in 2 separate Excel files. One map is to plot the time reported, and the other will map the specific crime.
Complete your 2 maps using the Plotting Map Template given below, and submit them to the team leader.

Your chief is asking for an analysis of the crime over the weekend. He has been receiving complaints from citizens that their area is not being covered to combat crime. He would like answers to the specific questions listed below.
Discuss the following questions on your group Discussion Board so that the team leader can compile the information to be used in the team paper. The answers to these questions are based on the crime and time mapping that you have finished for the team work.
- Is there an excess of suspicious person reports in one area? If so, why do you think that may be happening?
- Is there a lack of suspicious person reports in one area? If so, why do you think that may be happening?
- Is there a certain time for burglaries? If so, why do you think that may be happening? Is there a cluster for the following:
- Carjacking reports
- Domestic reports
- Home invasions
- Driving under the influence
- Are domestics related to one area? Why or why not?
- The chief needs to allocate his officers to certain areas. At what day and time would he or she increase patrol car activity and in what area?
- Give reasons to your chief as to why it would be advantageous to the department to have a computer-generated mapping system.
The team leader will take the crime map that the team deems correct and add it to the team paper along with the answers to the questions above.
Members of the team will address these questions using the crime mapping and time mapping that they made up for this group project. When you submit your replies to the team discussion board, upload your 2 files so that others can see your mapping.
