Crime Analysis the Job


Analysis of crime is a part of criminology that gives the Police Officers dependable data. Being capable of reading and understanding charts and graphs for a specific area is a task that takes a full time staff to accomplish. Summaries of criminal activity displayed in any geographical area can project helpful information for the Police Department and Government Officials. 

Some of the tasks Crime Analysis over see deal with the identification of the criminal activity for a specific geographical area such as the New York City. If criminal activity is up in New York City the information leads an analysis to query data about, what types of crimes are committed? Once the crimes are documented then one can move to specifics such as a vast info cell of gender, race, age, and other vital information that is connected to the criminal activity in the area. 

Separating the criminal information source by zone allows the Police to patrol a specific area for criminal activity that is common to the location. If there is a high level of drug solicitors in an area of Watts and Manhattan has a large number of users then one could assume to have Police Patrols between Watts and Manhattan to intercept the transport of drug trafficking between the two geographical areas, thus cutting the suppliers off. Having sources of information available to support your crime fighting theories can help in many situations. Some include vehicle theft, serial rapist, child abduction, and robberies.

Other geographical information such as economics of the area and social service information may come in handy. Analysis tools are capable of many different reporting analyses of crimes in specific areas. The new crime analysis software evaluates areas by producing charts, graphs and maps of  locations within your Police Departments geographical placement. Having the capability to create spread sheets and reports of areas with high and low levels of crime help explain the difference between areas allowing analysis to evaluate the problem areas identifying why criminal activity exists in them. Having the capability to make comparisons that are accurate allows the Crime Analysis to identify why the areas have high crime rates and why other areas have low levels of crime rates. Also being able to view the area on a map that shows the general layout such as housing, gas stations, shopping centers and other public facilities while tracking the Police Officer routes by (GPS) Global Positioning Systems gives a good idea of what criminal activity is happening and where.

The Analysis has to be well trained for any situation that may occur. They need to be able to identify and update the Police Force for what is currently going on in their sector. Some of the resources and analysis tools are difficult to use when matching data with reports and spreadsheets. Assessing the benefits of the change in response time when an analysis is on the job making sure that Police are patrolling the correct areas make the efficiency rate of the Police Department go up. Flexibility and creativity are a plus when dealing with analysis systems allowing the department head to make changes to the type of statistical  data  that is collected for processing these changes are necessary to produce the correct data reports.

Bomb Scene Investigation

The procedures of bomb scene investigation start with the collection of fragments left on the crime scene. Looking for an explosive device is a tedious job some of the fragments you might want to look for are piping, cables, blasting caps, wads such as C4, dynamite, and TNT.  In some cases, you may find gunpowder as an igniter for bombs.An explosion or point of impact will most commonly be in the area that has the most destruction.  You will find a black bang residue on the ground that leaves a clear open area where the exploding device, bomb or peripheral was placed. Finding residue is important to solving the case because once the fragments and residue are found you can analyze what type of explosive device the asylum used.Military weapons of mass destruction can be mortar rounds, sheet explosives, 40mm rounds with white phosphorous, and other remote and timing devices found on the scene.  Try to identify the Military round by its Nomenclature and DODIC (Department of Defense Identification Code). The DODIC may be present on the fragments and able to be traced to a weapon.
