Criminal Jusitice. The Criminal Justice System Process Research Paper

Criminal Jusitice. The Criminal Justice System Process - Research Paper Example Authorities mentioned that Phelps Collins got inside through some help from one of his friends and a brother to the owner of the townhouse. However, detectives did not expressly draw a clear connection between the staged break-in and the previous stabbing of Robert Wone. However, homicide detectives were looking into the burglary with the zeal of uncovering various potential leads. Wone was stabbed at the chest as he was visiting friends at the same home on the edge of Dupont Circle along the 1500 block of Swann Street NW. New details relating to the burglary later emerged through a number of interviews conducted much later (Klein &Schwartzman, 2006). Testimonies and court papers from a hearing for Collins the following week at D.C. Superior Court were also sources of information. Collins was later arrested on a burglary charge. Police maintained that Collins confessed to them that that Michael Price, the friend, had provided him with a key to the contended house as it belonged to Jo e Price, his brother. Police also added that Collins said that Michael Price was responsible for turning off the alarm immediately the two men broke into the house where electronics worth $7,700 were stolen. Case presented At the time, Michael Price was not yet charged in the burglary and he was not located to provide any comments. After the staged break-in, the detectives proceeded to the nearby pawnshops where they found two DVD players, an audio system among other stolen goods which led them all the way to Collins. In Calvert Street NW, the police found one of the CD changers as they searched the Collins's home. Collins had sold most of the other stolen items along the street for drugs or money, as the authorities speculated. A lawyer at one of the Washington firms, Joe Price, told police that he was not aware that Collins had done it even though he had heard the same through his brother (Klein &Schwartzman, 2006). This is according to information that was sourced from an affidavit the police filed after getting the search warrant for the residence of Collins. Joe Price also mentioned to the police that the brother was known to engage in drug abuse as well as hanging out with diverse subjects who we re adversely mentioned in drug usage on a frequent basis. Price directed the police to the fact that he did not avail permission to neither his brother nor Collins of entering his house and removing and later selling his property as stated in the affidavit. His public defender did not comment. Up to the point of the break-in, police expressed considerable doubt on the intruder theory. This is because there lacked an express sign of forced entry as the killer used a kitchen knife. Further, the crime scene seemed to be cleaned prior to the arrival of the officers as recounted by the police. Investigators convened a grand jury as well as enlisting the integral help of the respective departments of the FBI within the homicide. They also sought to keep high levels of control for the $1.2 million houses across several weeks after the killing while removing flooring, a chunk of the staircase, pieces of walls, sink traps and the washing machine searching for blood as well as any other evide nce (Klein &Schwartzman, 2006). Collins, who was at the time unemployed, had a criminal history which included four drug convictions between the years of 1998 and 2004 in the Montgomery and District as shown by the records. Authorities mentioned that most of the items taken from the burglary turned up at Pawnbrokers on 14th Street NW at Sam's residence which was only a few blocks away. The manager at the store, Sam Levy, said that Collins had previously pawned

Quantitative Methods and Analysis - Essay Example 190). where, Z is the value of the normal distribution table at given confidence level ? is the standard deviation and E is the desired precision For AIU, Confidence level is 95%. Z (Confidence level=95%) = 1.96 ? = $700 E = $55 Thus, it implies that the institute needs to sample 623 individuals to meet the original requirements of the sample. The sample size that is determined has a significant impact on the budget of the research. An increase in the sample size will mean that the institute will have to spend more amount for carrying out the research. If the budget of AIU is not enough to cover the entire sample of 623, the institute can reduce the sample size or lower down its conditions in confidence level or desired precision. If we see the normal distribution table, we see that the z value deceases with decease in confidence level (Levin & Rubin, 2007). In order to reduce the sample size, one option that AIU is having is to reduce its confidence level. Confidence level is a repr esentation of the surety of the data received. Confidence level can be defined as the likelihood of the true population parameter lying within the range specified by the confidence interval (Stattrek, 2011). Decreasing the confidence level will lead to decrease of the z value, which will reduce the sample size. ... crease the distance from the mean that is permissible for the mean dollars spent by each card holder to $70 at the same confidence level, the sample size becomes: We can see that a slight increase (from 55 to 70) in the marginal error that is acceptable to the researchers lead to a decrease in the required size drastically (from 623 to 385).

In a research using surveys a questionnaire is admin istered on a carefully identified sample of respondents (McQuarrie, 2006). Survey questionnaires are typically aimed at identifying particular respondent’s characteristics, attitudes or perception. Surveys find extensive application in areas such as market research, psychological studies, sociology and human resources. One example of a survey can be a survey in the area of market research, where respondents are asked to respond to their opinion about a particular product or service. Such surveys can be administered through questionnaires written on paper. Another type of survey can be the one used by the HR department of organizations to assess the employee satisfaction levels. These surveys can be administered as web-based surveys. Telephonic surveys can be administered to analyze the
