Polygraph In Police Work Case Study

In dealing largely with disorderly elements of the society, some people working in law enforcement may gradually develop an attitude or sense of authority over society, particularly under traditional reaction-based policing models; in some cases the police believe that they are above the law. In other cases, police corruption and misconduct may be explained by individuals and individual faults- behavioral, psychological, background factors, and so on.

The belief systems found in the police organizations is the idea that crime is only fault by police officers who dislike patrolling of their local communities. Police are above the law in a secrete brotherhood , while the general public are ignorant, obstructive and overly demanding. The anarchic ideas embedded into the officers can lead to misuse of power, misconduct and corruption.

There are many instances in which the polygraph is proven to be at fault such as with Cleve Backster. He was a polygraph examiner and believed strongly in the polygraph and its results. Backster one day decided to attach a houseplant that was in his office to the machine. He then would light the plants leaf on fire to see if the polygraph would have a spike in action. To his surprise as he struck the match the polygraph jumped signifying a response (Eells). Instead of considering that the polygraph went off randomly Backster instead assumed the plant had feelings and could even read his mind. This discovery lead to many scientific research projects in which scientists were unable to replicate Backster’s results. Rather than dismiss the event and polygraph as unreliable Backster dedicated the rest of his life to proving his discovery. The polygraph has been drilled into the minds of people as credible that taking it out of the justice system

This research question will clearly address the variations of police practices over the past 5 years in Baltimore City and Baltimore County, due to the recent incidents regarding police brutality and corruption. Using Chapter 12 Politics, Power, War, and Peace, will help show the relationships between politics in law enforcement and police officers, which deals with a lot of power and peace. Chapter 12 Politics, Power, War, and Peace, Section Cultural Controls in Maintaining Order states “Every culture has various forms of cultural control to ensure that individuals or groups conduct themselves in ways that support the social order. People who challenge or disturb the order face negative consequences” (W. Haviland; pg 315). In Baltimore

Eyewitnesses are critical to the criminal justice system, but there have been issues involving eyewitness testimonies, which occasionally cause them to be seen as unreliable. According to innocenceproject.org, 72% of DNA exoneration cases in the United States have resulted from eyewitness misidentification. This is concerning because in a study by Benton, Ross, Bradshaw, Thomas, and Bradshaw (2005), they examined jurors, judges and law enforcement’s knowledge about eyewitness issues. They found that those involved in the legal system are still very unaware of eyewitness memory research, and the reasons behind why eyewitnesses may or may not be considered reliable. There needs to be a way to increase reliability so that eyewitnesses are able to accurately recognize perpetrators and other important information to put the guilty people away, and to keep the innocent people free.

In the data-collection phase, the examiner will complete polygraph charts, the charts and questions will vary depending on different cases. The examiner then analyzes the collected data in the data analysis phase. The examinee then has the opportunity to explain or rationalize answers to different questions asked during the exam. Although some may criticize the polygraph tests, advances in technology, and science improves the polygraph exams. Multiple factors play a key role in the accuracy of a polygraph, including the experience of the examiner, the obediance of the examinee, and the way the exam is constructed. It is important to consider body language when interviewing examinees as well. This includes things that examinees may be saying, how they say it, and when they say it. One’s body does things that it cannot control, both inside and out, which plays an essential role in exams. When a polygraph test is administered perfectly, and appropriately the accuracy rate is above ninety percent. On the other hand, false positives on the polygraph exams may happen. A good examiner will try to identify, and get away from false positives. When Ruby has a false

Criminal justice majors have defined militarization of police forces as “the process whereby civilian police increasingly draw from, and pattern themselves around, the tenets of militarism and the military model” (Greenwald, 2014). Whereas, Kraska and Kappeler (1997) defined militarization as “a set of beliefs and values that stress the use of force and domination as appropriate means to solve problems and gain political power, while glorifying the tools to accomplish this [with] military power, hardware, and technology”. Militarization of police involves the use of military equipment and tactics by law enforcement officers (Balko, 2013), including such things as the use of armored personnel carriers, assault rifles, submachine guns, flashbang grenades, grenade launchers, sniper rifles, SWAT teams, etc. (Wood, 2014).

Law enforcement agencies in the United States reliance on the paramilitary structure model of the industrial and manufacturing era has become increasingly outdated and ineffective (Batts, Smoot, & Scrivner, 2012). Despite the change law enforcement agencies remain slow to adapt to

Furthermore, employers who identify with the above agencies, can only utilize (a type of lie detector), for certain job applicants, i.e., pharmaceuticals, dispensers, armored cars, and security (United States Department of Labor, 2015). Additionally, the law does allow private employers to administer a lie detector test if the following incidents occur, embezzlement or theft, which must fulfill two conditions, injury or economic loss (United States Department of Labor, 2015). Should culminating circumstances allow a polygraph test to take shape; the following standards of pretesting, testing, and post-testing will occur with a licensed and bonded professional examiner. Lastly, according to the United States Department of Labor (2015), “the Act, strictly limits the disclosure of information obtained during a polygraph test” (para.

A polygraph test or a lie detector is a device that measures and records variances in blood pressure, pulse and heart rate, while whomever is hooked up to it is asked a series of questions. There are different types of questions that are asked. There are relevant questions, control questions, irrelevant questions, and concealed information or guilty knowledge questions.

Polygraph test should not be held admissible in the court system because it use falsely and it dont always catch the lies that have be told .The person can pass the test even when the statement was falsely answer wrong.Also another thing when the person is taken the test they are watching their Heart rate, Blood pressure,Respiration, skin and etc.

The polygraph test is one of the most controversial criminal investigative techniques of all-time. From the initial years of the invention to today, there is not a consensus about the investigative tool. That is why there are many people for and against the administration of polygraph tests. Therefore, in order to develop a clear picture of the polygraph test the history of the test must be established. Although, there are many sources that have well documented concerns about the invention, the polygraph test is still around after almost 80 years.
