The stages of cybercrime investigations: Bridging the gap between technology examination and law enforcement investigation

Cybercrime investigation can be argued as still in its infancy. The technical investigation practices and procedures of global law enforcement are also still evolving in response to the growing threat of the cybercriminal. This has led to considerable debate surrounding the adequacy of current technical investigation models, examination tools and the subsequent capability of law enforcement to tackle cybercrime. To bridge the gap between low-level technology recovery and digital forensic examination, and to overcome the many technical challenges now faced by law enforcement; this paper presents an extended cybercrime investigation model capable of guiding the investigative practices of the broader law enforcement community. The Stages of Cybercrime Investigations discussed throughout this paper, demonstrate the logical steps and primary considerations vital to investigating cyber related crime and criminality. The model is intended to provide both technical and non-technical investigative resources, covering mainstream law enforcement, partner agencies and specialist technical services, with a formal and common structure when investigating the complex technical nature of cybercrime. Finally, the model is further aimed at providing cybercrime investigators with a means to consolidate understanding, share knowledge and communicate the resulting outcomes as an investigation moves through each relevant stage.     

Law enforcement organizational behavior and the occurrence of post-traumatic stress symptomology in law enforcement personnel follwoing a critical incident

Research by Evans and Coman (1993), Sewell (1984), and Gudjonsson and Adlam (1983) suggests that being shot in the line of duty or the shooting of a partner are often ranked by officers, despite their infrequent occurrence, as the most stressful field events. This study was designed to elucidate factors within the organizational structure of law enforcement, other than the incident itself, which promote ineffective coping and increases in PTSD-like symptomology in police officers. This study found that both police officers, and the organization in which they work, practice predominately ineffective emotion-focused coping strategies following an officer-involved shooting. Possible links between organizational behavior and long-term post-traumatic symptomology were discovered; it appears that officers have readily available models of poor coping responses merely by imitating the behavior of their organization.

An experimental validation study of the SASSI: Predicting alcohol related behavior in law enforcement applicants

This investigation evaluated the validity and utility of two versions of the Substance Abuse Subtle Screening Inventory (SASSI, SASSI-2; Miller, 1988, 1996) for determining alcohol related risks among law enforcement applicants. Three hundred and seventy applicants were assessed in two separate studies to determine the degree to which SASSI classification corresponds with self-reported a) number of drinks per month, b) admissions to having recently driven while intoxicated, and c) adminissions to having ever been worried about one's drinking behavior. Analyses revealed a pattern of poor discrimination for both versions of the SASSI, raising concerns regarding its use as a clinical assessment tool.     

Pirates,prisoners, and preliterates: anarchic context and the private enforcement of law

This paper investigates institutions that develop to strengthen or expand the discipline of continuous dealings as a mechanism for privately enforcing law. I consider three such institutions in three different anarchic contexts: that of Caribbean pirates; that of drug-dealing gangs and prison inmates; and that of preliterate tribesmen. These cases highlight several ways in which different anarchic contexts give rise to different private law enforcement institutions. The varieties of private law enforcement institutions that emerge in different anarchic contexts reflect the particular problem situations that persons who rely on those institutions confront in their attempts to protect property rights without government.     

The maturity model in practice: chaos,reaction, evolution,and inclusion in law enforcement analytic models

This article discusses the analytic maturity model that was developed by the Vancouver Police Department. The maturity model was developed to self-asses the agency’s analytic process and determine to what degree it was operating. The article explores the various stages of the analytic model and applies them to the Royal Canadian Mounted Police and FUSION CENTERS in an attempt to show how the maturity model can be utilized by other agencies as well in self-assessing their analytic process. The article concludes by suggesting best practices which are to be utilized in conjunction with the maturity model.     

A study of amnesia in homicide cases and forensic psychiatric experts' examination of such claims

About one third of defendants in homicide cases claim amnesia during the time of their alleged act. Examining the authenticity of claimed amnesia is a special challenge for forensic experts. Because the experts' conclusions have legal implications, it is useful to study the characteristics of defendants who claim amnesia regarding a homicidal act and how forensic experts assess these defendants' claims. The forensic psychiatric reports from 2001 to 2007 on 102 Norwegian defendants charged with homicide were assessed quantitatively with a structured rating form. Due to multiple comparisons p of .003 was chosen. Twenty-six defendants claimed partial and 17 claimed total amnesia. No significant differences in the characteristics of the defendants were found between the partial, total, and no amnesia claiming groups. Claims of partial or total amnesia did not change the procedures and content of the forensic experts' examination. A memory test was applied in only one case. Despite the seriousness of the crime and the difficulty of assessing amnesia, the experts did not apply psychological testing of memory function or appropriate tests of possible malingering. Guidelines or standardized procedures for evaluation of defendants who claim amnesia should be developed. This could eventually contribute to more reliable and valid evaluations by forensic experts and increase the probability of just court outcomes.     

Administrative,legal, and ethical practices in the psychological testing of law enforcement officers

Recently, more law enforcement agencies have chosen to use psychological testing as an important component of their preemployment screening programs. Important legal and ethical issues have been raised by the increased use of psychological testing for this purpose. These issues include the applicant's right to privacy, the validity of the psychological instrument(s) used, the definition of what constitutes an “unsuitable” candidate, and the existence of racial and/or sexual bias. This article presents ten suggestions that address some of these issues and that may aid law enforcement agencies in adopting the spirit of the Uniform Guidelines on Employee Selection Procedures and other psychological-testing standards.     

A re-examination of the MMPI-2 aggressiveness and immaturity indices in law enforcement screening

This study reports an analysis of Bartol's (1991) Immaturity Index and Hargrave and associates' (1988) Aggressiveness Index as a measure of police conduct. The correlations between the supervisory ratings and the Immaturity and Aggressiveness indices were examined for 1020 law enforcement officers. The results showed that Immaturity Index was related to termination for failure to complete training and insubordination. The Aggressiveness Index was related to a termination for failure to complete training and several other problematic police behaviors, but was not found to be specifically linked with acts of aggression. Implications for using these two indices in law enforcement selection are discussed.

Battered wives,lawyers, and district attorneys: An examination of law in action

The legal services received by 146 Milwaukee women who had been beaten by their husbands, but had been free of the violence for at least a year, are described and evaluated. Of these women 106 recieved legal help in connection with at least one battering incident. Some women saw more than one member of the legal profession, so the total number of legal contacts among the 106 women was 255. There is evidence that lawyers and district attorneys were most likely to be used by those battered women for whom the use of personal strategies and informal help sources (such as family and friends) were ineffective in combatting the violence. Contrary to the negative image of lawyers and district attorneys found in the literature on wife beating, most legal service contracts were rated as very or fairly successful by the battered women. The more difficult and severe the situation, the higher the success ratings given to lawyers and district attorneys by their clients. Despite the generally positive reactions that most beaten women had to lawyers and district attorneys, there were many negative incidents reported, including district attorneys who refused service or discouraged battered women from filing charges, and lawyers who sided with the aggressors or attempted to meet their personal and professional needs at the expense of their clients. These incidents remind us that it would be useful to educate legal professionals about the nature of family violence, the situation and needs of battered women, and the legal and ethical responsibilities that lawyers and district attorneys have when they are contacted by battered women.     

The prediction and control of organized crime: A risk assessment instrument for targeting law enforcement efforts

Linking isolated instances of organized crime in a systematic way can inform law enforcement in identifying high-risk activities and markets and prioritizing them according to objective factors known to be associated with organized crime. There are five ways in which risk assessment organized crime can be achieved. Improvements to data collection, utilizing a team approach to gather information, identifying common elements in organized crime incidents, understanding the parameters of a risk assessment instrument, and connecting organized crime risk assessment to the implementation of law and policy are practical ways in which organized crime activity can be better anticipated, investigated, and prevented. Connecting isolated incidents to organized crime through better information from offenders, victims, and police is possible with teams of investigators, researchers, and analysts. An organized crime risk assessment tool is presented that offers systematic analysis of opportunity factors, the criminal environment, and harm potential among the seventeen risk factors identified. Risk assessment can be used to evaluate the influence of organized crime in local jurisdictions, and the impact of new laws and policies that affect commerce and criminal opportunities.     

Cumulative career traumatic stress (CCTS): A pilot study of traumatic stress in law enforcement

The present study measured the existence of traumatic stress symptomatology as reported by certified law enforcement officers within the State of Delaware. A questionnaire was devised which documented age, sex, race, education, years of service, marital status, children, rank, position, and shift work. The questionnaire was divided into parts which assessed the exposure and the frequency of specific traumatic incidents experienced in the line of duty, and the frequency of experienced traumatic symptomatology criteria: re-experiencing, numbing, and arousal.     

Cops and cameras: Officer perceptions of the use of body-worn cameras in law enforcement

PurposeThere has been a recent surge in the adoption of and media attention to the use of body-worn cameras in law enforcement. Despite this increase in use and media attention, there is little to no research on officer perceptions of body-worn cameras.MethodsThis study relies on baseline data of officer perceptions toward body-worn cameras collected from surveys administered to Orlando Police officers who are participants in a randomized experiment evaluating the impact of body-worn cameras (Taser AXON Flex) in law enforcement.ResultsResults suggest that police officers are, by and large, open to and supportive of the use of body-worn cameras in policing, they would feel comfortable wearing them, and that they perceive a potential for benefits of body-worn cameras in improving citizen behavior, their own behavior, and the behavior of their fellow officers.ConclusionsOfficers are generally supportive of body-worn cameras, and they hold perceptions that these devices can be beneficial in positively affecting relevant outcomes. Study limitations and implications are also discussed.     

Reflections on variability in the blood–breath ratio of ethanol and its importance when evidential breath-alcohol instruments are used in law enforcement

Variability in the blood–breath ratio (BBR) of alcohol is important, because it relates a measurement of the blood-alcohol concentration (BAC) with the co-existing breath-alcohol concentration (BrAC). The BBR is also used to establish the statutory BrAC limit for driving from the existing statutory BAC limits in different countries. The in-vivo BBR depends on a host of analytical, sampling and physiological factors, including subject demographics, time after end of drinking (rising or falling BAC), the nature of the blood draw (whether venous or arterial) and the subject’s breathing pattern prior to exhalation into the breath analyzer. The results from a controlled drinking study involving healthy volunteers (85 men and 15 women) from three ethnic groups (Caucasians, Hispanics and African Americans) were used to evaluate various factors influencing the BBR. Ethanol in breath was determined with a quantitative infrared analyzer (Intoxilyzer 8000) and BAC was determined by headspace gas chromatography (HS-GC). The BAC and BrAC were highly correlated (r = 0.948) and the BBR in the post-absorptive state was 2 382 ± 119 (mean ± SD). The BBR did not depend on gender (female: 2 396 ± 101 and male: 2 380 ± 123, P > 0.05) nor on racial group (Caucasians 2 398 ± 124, African Americans 2 344 ± 119 and Hispanics 2 364 ± 104, P > 0.05). The BBR was lower in subjects with higher breath- and body-temperatures (P < 0.05) and it also decreased with longer exhalation times into the breath-analyzer (P < 0.001). In the post-absorptive state, none of the 100 subjects had a BBR of less than 2 100:1.     

Social disorganization, marriage, and reported crime: A spatial econometrics examination of family formation and criminal offending

It has long been documented that “marriage matters” for a variety of reasons. Furthermore, there has been considerable debate over the causal relationship between marriage and a number of its associated correlates, most often related to social processes of health behaviors, criminal involvement, and achievement. While most research associated with marriage and crime is concerned with the individual, little is understood concerning the ecological effect of marriage rates. Using data from the U.S. Census Bureau and the F.B.I.'s Uniform Crime Reporting Program (UCR), this study tests such relationships through the implementation of spatially-centered analytic approaches concerning the potential independent effects of marriage rates within a social disorganization context. It is important to understand such aggregate level effects in the face of the existing literature, which relies heavily on relational associations and is subject to ecological fallacy. Analytic techniques incorporate Exploratory Spatial Data Analysis (ESDA) and spatial regression.     

Predicting law enforcement confidence in going ‘hands-on’: the impact of martial arts training,use-of-force self-efficacy,motivation, and apprehensiveness

ABSTRACT

In law enforcement, there are situations allowing officers to gain control of suspects by going ‘hands-on,’ or physically placing someone in custody beyond simple handcuffing. While much empirical attention is placed on more lethal use-of-force (UOF) measures, little is known about going hands-on. This is concerning considering when force is used, it is almost always with the use of hands, fist or feet only. The purpose of this pilot study is to examine whether martial arts training (MAT) and UOF self-efficacy predict confidence in going hands-on, after accounting for perceived motivation and apprehensiveness. It draws from an online survey, and a non-random subsample of 1,064 un-ranked patrol duty officers in the USA. Results indicate that MAT and high perceived UOF self-efficacy safely predict confidence in going hands-on, even after accounting for perceived motivation and apprehensiveness. Nonetheless, apprehensiveness, but not motivation, remains a strong predictor of not being confident in going hands-on.     

Absolute and relative support among citizen-voters for local law enforcement agencies: Correlates with selected dimensions of political ideology

During the last twenty years numerous studies have been published regarding public support for local law enforcement agencies. These studies have typically focused on three determinants of support-the social status of the citizen, citizen fear or actual victimization of crime, and the nature or frequency of citizen-police contacts. This somewhat exploratory research evaluates the impact of political ideology upon citizen support for law enforcement agencies. The thrust of the investigation builds upon much more limited considerations of ideology in earlier studies. An assessment and comparison of support according to absolute/diffuse measures and relative/specific measures of citizen-voter support are presented. Political ideology is defined in the context of contemporary liberal-conservative perspectives and operationalized according to nominal (self-identification)and issue-oriented techniques.     

Breathalyzer accuracy in actual law enforcement practice: a comparison of blood- and breath-alcohol results in Wisconsin drivers

Breathalyzer and blood-alcohol results from drivers arrested for operating a motor vehicle while intoxicated and for related offenses were compared during a two-year period. Four hundred and four pairs of breath- and blood-alcohol results from specimens collected within 1 h of each other were studied. Blood-alcohol concentrations ranged from zero to 0.421% weight per volume (w/v). Breath-alcohol concentrations ranged from zero to 0.44 g/210 L. The mean Breathalyzer result was 0.16 g/210 L. The mean blood-alcohol result was 0.176% w/v. Compared to the blood-alcohol result, Breathalyzer results were lower by more than 0.01 g/210 L 61% of the time, within 0.01 g/210 L 33% of the time, and higher by more than 0.01 g/210 L 6% of the time.
