DNA evidence is vital in helping the search for truth in many criminal cases such as a murder case, rape case or up any serious case. The offenders of these cases often committed because they do not want people to see their crime event’s doing. Some case against life, the offenders are a highly skilled and cover their actions by destroying evidence. In rape case, the rape scene or event which not only affects the body and mind of a rape victim, but also affect the confidence of the society toward with law enforcement.
These profiles fall between psychology and law enforcement, some call it “investigative psychology” while another refers to it as “crime action profiling”. The main connection, the common goal they all share; help investigators examine evidence, narrow down a suspect pool, or give helpful tips on how to interrogate a suspect already in custody. Psychology is used to investigate behavioral patterns, personality traits, and psychopathologies. Demographic variables including age, race, and geographical locations are also used in the profiles. Recently criminologists, law enforcement officials, and psychologists have all teamed together to take criminal profiling, which started out as an art and transform it into a reliable science.
To start with, do you know that what is offender profiling? Different authors have defined offender profiling by using different terms such as specific profile analysis, psychological profiling, criminal profiling and criminal personality profiling. However, the basic concept of definitions remains the same (Jackson and Bekerian, 1997). Beauregard, Lussier and Proulx (2005) state that offender profiling provides some descriptive information on the behaviors and individuality of an offender. Number of suspects can be narrowed and finally solve the cases by analyzing the crime scene features.
Thesis statement: Police should wear body cameras because playing body cameras could improve the public’s view of police by showing the human side, help to provide evidence when a person may not be able to, and it protects the officers and public both. Cameras Imagine there is a huge case going on where a police officer is coming under question on if dealt with a potential suspect in the correct way. Now think about the money being used to provide lawyers, a judge, a jury, etc., to handle the high profile case.
There are some of the classic patterns such as directionality, cast-off bloodstains, swipe marks, pattern transfer, saturation, arterial patterns, drip patterns and other examples of bloodstain dynamics, which should be noted and documented by the crime scene investigator, when at the scene. (Bloodstain Pattern Analysis). (n.d.). Recording the bloodstain patterns, in the scene, is one of the important documentation of the investigation. This documentation of the investigation should be accomplished before anything is touched or moved at the scene.
Police should wear body cameras because they can improve the public view of police by showing the human side which can help to provide evidence when a person may not be able to, and it protects both parties which both are a vital part of policing. Police officers should be required to wear body cameras so that their use of force can be documented and judged. It's time to think about what measures can be put into place to hold all law enforcement accountable. As a person who has had two friends experience police brutality at the hands of the police it's time to enforce the wearing of the body cameras. Police in every state should agree on letting officers wear an on officer recording system, or body cams that are the size of a ink pen that can be attached to hats, helmets, or collars of their uniforms.
Gottfredson and Hirschi (1990) acknowledged within their self-control theory that the opportunities for crime are readily accessible and crime is typically not difficult to perform. Yet, Gottfredson and Hirshi focused on the lack of self-control as the cause of crime rather than the opportunities for crime. Cohen and Felson (1979) in describing the routine activity theory, later stated that motivated offenders must find suitable targets that lack guardians in order for crime to occur. Situational crime prevention strategies were the first to focus on specific crimes, the environment and the reduction of crime opportunities.
Speech Outline Title: Body Cameras I. Introduction Attention-getter: Body cameras were used because of Michael Brown’s death and police misconduct. B. Significance Body cameras may increase police accountability and protect them from accusations. C. Credibility: My interest in this topic is due to the latest deadly encounters with police officers and improving the communities’ safety.
What does Patrol do? Being that patrol officers are most commonly encountered by the public, their duties consist of responding to calls for service, resolving disputes, taking crime reports, making arrest, conducting traffic stops, and other crime prevention measures. Being that patrol officers have to know geographic areas well it is important that they are the first to arrive on the scene of any incident. As an officer it is also important that they take precaution measures to everything they do in the crime scene area; what such an officer does or fails to do at the scene can and will greatly influence the outcome of any investigation. As an active member in the community and a person who is in the field daily, he/she is often closest to potential crime and may have developed contacts who can provide certain information
First, is letting the community know what the police are doing. Another, to find truth or false statements or accusations. First, of all, body cameras can show the community what the police are doing. First, if the community wants to know what the police are doing, body cameras are a great way to show it.
Blood spatter analysis is the interpretation of bloodstains at a crime scene in order to recreate the actions that caused the bloodshed. By using the analysis they observe the spatter of the blood, the investigators and forensic scientists can determine how the victim was wounded, what weapons were used and where the object hit the body. Evidence is really important because it can be either stopping the criminal or letting him
There are many important factors in crime scene investigation, one of those involves serology and observing the blood spatters at a crime scene. Many steps are taken when dealing with blood at a crime scene, some of which are if the substance is actually blood, blood typing, discerning the origin of the blood, the direction of travel of the bloodstain, what weapon would have caused the bloodstain, etc. Serology and dealing with bloodstains can be a very difficult task for criminalists because blood also deals with DNA, what type of blood it is, identifying who the blood belongs to, what caused the bloodstain, and what direction it originated from. To understand serology, it is probably best for one to understand the nature of blood first.
Tactical crime mapping is the most concerned kind of crime mapping in light of the fact that it manages the most exceedingly terrible of the most exceedingly terrible crimes that is a quick danger to the general population, for example, homicide, assault, theft, and thievery. The crime expert will assemble the patterns by observer accounts, the weapon utilized, the suspect's physical depiction, and numerous different likenesses put into the record for deciding the suspect of the crimes carried out. At that point amid this sort of crime investigation the cops will be more aware of specific individuals who look like the suspect's depiction and the organization will have more cops in that specific territory to prevent the crime from happening
The field of criminal justice needs theories to exist in the real world. The course Criminal Justice 325 helps future law enforcement agents understand why theory is needed and how to use them. Theories go through the steps of the criteria of theory evaluation to even become a theory. This is desired because if there are no guidelines theories would be all over the place. With theories about crime come crime itself.
The next topic to show why DNA testing is important to law enforcement is the unanalyzed evidence stored away hoping one day to be tested. There was a study done showing over a time frame of five years that there was about 40% of unanalyzed rape and homicide cases that had DNA evidence waiting to be tested. They suspect that there maybe a few causes for this kind of problem. These unanalyzed cases are a part of backlogs and they are terming as cases of justice denied. Some speculate that the investigating officer can be a cause of why evidence is not tested.
