Legal Protection For Advocates Who Are Considered Not In Good Faith For Alleged Obstruction Of Justice In Corruption Cases

Advocates as one of the professions in the field of law in their duty to defend clients both inside and outside the trial are equipped with privileges in the form of legal protection (immunity), but often these privileges are abused by advocates by obstruction of justice especially in cases of corruption crimes that aim to prevent clients from being investigated by Police Investigators, the Prosecutor's Office or the KPK. There are differences in the parameters of the assessment of good or bad ethics by an Advocate carried out by the Investigator so that it is considered to be an obstruction of justice so that there is a conflict between the legal norms contained in Article 16 of Law Number 18 of 2003 concerning Advocates and the reality that occurs in the field. The problem that causes advocates to be considered not to be good at obstructing justice in corruption cases is due to the absence of assessment parameters of advocates who are not in good faith and the absence of legal protection for advocates who are suspected of obstruction of justice, especially in corruption cases. The method used in this study is normative - empirical legal research, using a case approach, a legislative approach (statue approach) and a conceptual approach (Conceptual Approach). This study aims to examine the assessment parameters of advocates who do not have good faith against the suspicion of obstruction of justice by investigators and to find out the analysis of legal protection (immunity rights) owned by advocates who are considered to have no good faith by committing obstruction of justice, especially in cases of corruption. The results of this study are that the criteria for Advocates who are considered not in good faith are violations of the code of ethics, laws and regulations, oath or promise of Advocates as well as the value of feasibility and propriety. In addition, in order to create legal protection and certainty, a special institution such as the Advocate Honorary Council is needed which aims to determine whether the actions of the Advocate who are considered not to be in good faith are contrary to the etic code or laws and regulations or not.

Committing Homicide After Drinking: The Characteristics of Self-Reported Alcohol-Involved Homicide Offending

ABSTRACT It is well established that alcohol use is associated with homicide (e.g. Kuhns et al. 2014; Parker et al. 2011). However, much of our knowledge of alcohol-involved homicide is based on official data. Self-report data obtained directly from offenders about their consumption of alcohol immediately prior to committing homicide provide valuable information that complements data from official sources such as details emerging from police investigations and court proceedings. However, such data are rare. This study analyzes self-report data collected through face-to-face interviews with 205 men and women convicted of murder or manslaughter in Australia, of whom almost half (43.4%) reported use of alcohol prior to the homicide. The strongest predictor of alcohol-involved homicide was ongoing alcohol problems, speaking to the importance of prevention strategies targeting the entrenched nature of substance misuse. Furthermore, alcohol-involved homicides were nighttime events, committed in public places by older offenders using knives. Though such variables appear indicative of impulsiveness, a measure of self-control did not distinguish between alcohol-involved and not alcohol-involved homicide. Further investigations into the role of self-control on alcohol and violence are necessary.

Deadnamed and Denied Justice: The Role of Deadnaming and Other Factors in Transgender Homicide Clearance

Fatal violence against transgender people is a critical issue in contemporary America. There is also significant reason to believe that many transgender homicides are left unsolved. There has, however, been no systematic analysis of these patterns. This study uses data from a newly-collected, comprehensive database of transgender homicides occurring between 2010 and 2021 to conduct logistic regression analyses predicting the likelihood of clearance by arrest, accounting for the presence of deadnaming and various victim sociodemographic characteristics. Taken together, our research identifies two clear findings regarding the clearance of transgender homicide. First, we observe clear differences in the frequency of deadnaming by the police according to victim characteristics, such that incidents involving Black victims and victims with a history of involvement in sex work are more likely to involve deadnaming. Second, we find that homicide incidents in which transgender victims are deadnamed by the police are significantly and substantially less likely to be cleared by arrest, relative to transgender homicides. These findings suggest the critical importance of eliminating instances of deadnaming among police investigations of transgender homicides, not only for moral reasons, but also as a clear barrier to police efficacy in solving murder cases.

Information Hiding and Digital Transformation: Strategies for First Information Reports (FIR) and Police Records

Throughout the last few years, it has become increasingly obvious that everything is moving from a traditional world to a digital one. In order for police organizations to remain competitive, they need to keep up with the rapid technological advancements that are taking place in order to stay ahead of the competition. The First Information Report (FIR) in South Asian and Southeast Asian countries is a legal document which provides police with information about an apparent crime which has been reported to them by the victims of crimes. It is part of the police's investigation process. The police still have a difficult time getting accurate information from victims in terms of what exactly occurred during the incident, which makes getting accurate information from them very difficult. The filing of a police report presents a wide range of challenges as far as police organizations are concerned. There is a major challenge in the investigation of crimes involving victims concealing information about critical knowledge subsets and the complexity of these sets from the police authorities. For police records to be managed effectively it requires an organisational transformation that is driven by well-established digital strategies that offer an overall view and full transparency of both the knowledge about FIRs as well as the access to them. There is no doubt that an organization such as a police force cannot underestimate the importance of adopting the right technologies and frameworks as part of its digital transformation strategy in order to be able to meet the needs of its customers. The challenge of solving the long-standing problem of police organizations with limited resources concealing knowledge is going to be a long-term task that can be quite challenging. This paper presents several strategies and best practices which can be adopted by law enforcement organizations so that they can successfully transform digitally and achieve their goals through the implementation of these strategies and best practices.

Geographical classification of population: Analysis of amino acid in fingermark residues using UHPLC-QQQ-MS/MS combined with machine learning

ObjectiveTo determine the living regions of individuals based on amino acids in fingermark residues and to establish a rapid and accurate regional classification method using machine learning. Methods: A total of 71 fingermark donors from six different provinces in various regions of China were selected. The content of 18 amino acids in their fingermarks was detected using UHPLC-QQQ-MS/MS. Classification models were established using various machine learning algorithms, and the cross-validation accuracy of 72 combinations, including feature engineering, classification algorithms, and optimization algorithms, was compared. Results: UHPLC-QQQ-MS/MS successfully quantified 16 amino acids. Significant differences in the relative content of amino acids were found between the fingermarks from the eastern and western regions of China, as well as among neighboring provinces. The combination of SFS+SVM+BO was identified as the optimal classification model, achieving an accuracy of 90.14%. Conclusion: The study found regional differences in the relative content of amino acids in fingermarks and established a regional classification method combining UHPLC-QQQ-MS/MS and machine learning. The method developed in this study can be applied to incomplete or distorted fingermarks, and the experimental results can be directly used in police investigations. This research uncovers the multidimensional information carried by fingerprint substances, demonstrating innovation and application value. It not only saves and shortens investigation time and provides investigative leads, but also enables previously unusable physical evidence to play a role again, enhancing the profiling of suspects.

Psychosocial characteristics of suicide deaths by regional types in Korea: An analysis based on population inflow and outflow.

This study aims to investigate the psychosocial characteristics of suicide deaths in Korea according to population inflow and outflow, and to identify high-risk suicide groups by regional type in order to establish tailored suicide prevention plans for each region. The analysis included 4193 suicide deaths from four regional types in Korea. The data source was a comprehensive survey of suicide deaths through police investigation records from the Korean government. The analysis involved collecting demographic variables, suicide-related variables, and stress variables at the time of death for suicide deaths in each region and conducting cross-analysis and multinomial logistic regression analysis. Across all regions, factors such as male gender, unemployment, hanging in one's own home, and mental health problems were prevalent. However, in population-inflow urban areas, early-middle age and economic problems were higher, in population-outflow urban areas, late-middle age and economic problems were more prominent. Additionally, in both inflow and outflow rural areas, there was a relatively higher proportion of old age and physical health problems. This study is significant for confirming common and specific factors influencing suicide in each region, and for proposing considerations when formulating tailored suicide prevention plans for local communities.

Economic burden of suicide in Sweden in 2022

Abstract Background Suicide and suicidal behaviors bring massive human, social and economic impacts. Estimates of the cost of suicide can give some guidance as to where research on developing new interventions might be focused to give the greatest potential gain. The aim of the study is to quantify the economic cost of suicide in Sweden in 2022. Methods Incidence of suicide attempts and mortality due to suicide, intentional and undetermined (ICD10 X60-X84 and Y10-Y34) were sourced from the Swedish National Board of Health and Welfare databases for 2022. Cost were estimated from a societal perspective, including costs for inpatient and outpatient care, medication, police and justice activities as well as productivity losses due to early mortality. Results In 2022, a total of 1,569 suicide death were registered in Sweden (1,102 men and 467 women). The incidence rate remains stable during the last ten years, 17 death per 100 000. In total, 18,854 patients (10, 359 women and 8,459 men) were treated in inpatient and outpatient hospital care with suicide-related diagnoses, generated 32,843 days in inpatient care and 11,471 outpatient care visits. Direct costs for suicide death including forensic examination, emergency services, police investigation and property damage were estimated as €6,02 million, while indirect costs for productivity losses totaled €690 million. Direct healthcare costs for suicide related treatment were estimated at €54.3 million. Overall, suicide and suicide attempts cost around €750 million per year to society. Conclusions Estimates of the economic burden of suicide are needed for the Swedish setting, and these amounted to €60.3 million in direct costs and €690 million in indirect costs in 2022. The cost might be underestimated because the societal cost of suicide bereaved persons was not considered. These cost estimates can provide useful inputs to a cost-effectiveness analysis of a specific preventive intervention, and to its subsequent evaluation. Key messages • Economic burden of suicide is substantial for society. • Public health policies aimed at the prevention of suicide should be increased.

The police investigation is illegal and illegitimate

The Public Prosecution Service, which is the exclusive holder of public criminal action and external control of police activity, among other duties, and the police are responsible for investigating criminal offenses. That said, the aim of this research is to demonstrate that the Public Prosecution Service has been treated as a mere opinion-forming body in criminal cases, given the understanding of criminal judges and also of the Legislative Branch, contrary to the Federal Constitution of 1988. In this regard, the Code of Criminal Procedure places the Public Prosecution Service in a situation of non-ownership in the conduct of cases, through various provisions of this code, when, notably, it allows the criminal judge to superimpose his decision on the theses of the Public Prosecution Service. As far as the legislative branch is concerned, the enactment of laws still does not respect the 1988 constitutional provision on the role of the Public Prosecution Service. In addition, external control of police activity must guarantee the constitutional legality and legitimacy of the greatest instrument for investigating crimes, the Police Inquiry, according to Article 129, VII of the Brazilian Federal Constitution. The absence of external control compromises the quality of evidence and the effectiveness of criminal justice, confirming the urgent need to implement regulatory mechanisms that ensure efficient control of police activity, resulting in improvements in public safety and, above all, in the legitimacy of the Brazilian justice system.

Collaborative interviewing of eyewitnesses: a field study

Purpose When eyewitnesses talk to each other after witnessing a crime, they can contaminate each other’s memory. However, laboratory research shows that collaborative interviewing can also result in correction of mistakes and retrieval of more new information. The aim of this study is to examine whether these laboratory findings would generalise to real police interviews in The Netherlands. Because little is known about which interviewing techniques Dutch police detectives use, the secondary aim was to examine how Dutch detectives approach individual and collaborative eyewitness interviews. Design/methodology/approach In a field study, witnesses of serious incidents (e.g. police shooting) were interviewed individually and then collaboratively by real investigators, resulting in 15 interviews of 1–2 h each from five witness pairs (5,534 details in total). Transcripts were coded for detail type, forensic relevance, verifiability, retrieval strategies and interviewing techniques. Results were described using both quantitative descriptive data and a qualitative analysis of interview excerpts. Findings On average, collaborative interviews resulted in 131 new details, over half of which were considered highly relevant to the police investigation. Interview excerpts demonstrated how content-focused retrieval strategies (acknowledgements, repetitions, restatements, elaborations) can elicit new and highly relevant details. Interviewers mostly asked clarifying questions and equal numbers of open, closed and yes/no questions, but rarely allowed for uninterrupted free recall. Interviewers asked a higher proportion of open questions during collaborative interviews than during individual interviews. Research limitations/implications Limitations included the small sample size and lack of a control condition. Originality/value To the best of the authors’ knowledge, this paper is the first to investigate the effectiveness and feasibility of the Collaborative Eyewitness Interview in real-world settings.

Analysis of the Effeectiveness of the Integrated Law Enforcement Center (Gakkumdu) in Criminal Enforcement of the 2024 Election in Central Java based on the Principle of Legal Certainty

This study aims to analyze and examine the effectiveness of the Integrated Law Enforcement Center (Gakkumdu) in criminal enforcement of the 2024 Election in Central Java. This type of research is empirical or non-doctrinal law, the nature of analytical descriptive research. Using a qualitative approach with primary data from interviews and observations. Secondary data from books, scientific journal articles and legislative review. The results of the study show that the Central Java Gakkumdu Center has carried out its functions and authorities as a center for criminal law enforcement activities in accordance with the Election Law and Perbawaslu, but it has not been effective and legally certain. Because in handling election crime cases in 35 districts/cities as many as 110 cases, only 5 cases have permanent legal force, 2 cases stopped at the Police investigation, and 103 cases stopped at the discussion of the Gakkumdu Center. The causal factors are not in accordance with the theory of the legal system of law: (1) Legal substance: (a) the time to handle the case of election crimes is short (Speedy trial), (b) the legal subject of the perpetrator of the election crime is not fulfilled, (c) lack of evidence in the investigation of election crimes, and (d) difficulties in finding witnesses in the investigation of election crimes. (2) Legal structure: (a) many institutions in the Gakkumdu Center make coordination difficult, (b) different perceptions between institutions in the Gakkumdu Center make it difficult to determine election crimes, (c) the Gakkumdu Center is a non-institutional coordination forum in election crime enforcement, (d) the election crime enforcement coordinator Bawaslu only forwards reports and not as an election crime investigator. (3) Legal culture: (a) lack of understanding of election crime violations, (b) lack of public awareness of reporting election crimes to the gakkumdu center, (c) lack of public willingness to witness election crime cases, and (d) weak legal awareness of election participants to comply with the election law. The solutions to overcome the ineffectiveness of the Gakkumdu Center in election crime enforcement in the future: (a) the need for a single institution in election crime enforcement, and (b) the strengthening of Bawaslu's authority in election crime enforcement

The Court of Justice in Staatsanwaltschaft Berlin v. M.N. (EncroChat): From cross-border, data-driven police investigations to evidence admissibility

The ruling of the Grand Chamber of the Court of Justice of the EU (CJEU) in Case C-670/22 Staatsanwaltschaft Berlin v. M.N. addresses the realities of data-driven police investigations in the light of the Directive 2014/41/EU on the European Investigation Order (EIO Directive). In particular, it examines the cross-border, digital investigation of the encrypted communication network EncroChat and the use and sharing of intercepted telecommunication data in criminal proceedings. In doing so, the CJEU offers clarifications as to the interpretation of the term ‘issuing authority’ under the EIO Directive and the proportionality requirements for issuing an EIO, taking into account its prior jurisprudence on the implications of access to traffic and location data for the private life of the persons concerned. More importantly, this CJEU ruling takes a stand on admissibility of intercepted data as evidence in criminal proceedings, considering the technical complexity of contemporary investigation measures and the secrecy of said police methods. Overall, although this judgment seems to hold no great surprises regarding the interpretation of the EIO Directive's provisions, it underscores the important role of the national legislator and national courts in striking the right balance between rearing the rewards of data-driven policing and safeguarding defence rights.

Estimation of Stature from Percutaneous Upper Limb Measurements in the North Indian Population

Background: In the field of forensic anthropology, stature estimation plays an important role in the identification of unknown dismembered bodies and skeletal remains. When forensic experts find body parts during a police investigation, their first task is to determine the age, sex, and height of the person. They assist law enforcement by using scientific methods in criminal cases. Material and Methods: A cross-sectional study was carried out in the city. Measurements were taken on both the left and right sides of all males. The sample size was 563 individuals aged between 20 and 40 years. Accurate measurements of five upper extremities and stature were measured with the help of an Anthropometer and Sliding calliper. Results: The correlation observed between stature and upper limb showed varying degrees of correlation, ranging from moderate to strong 0.315 to 0.859. The precision of these equations was established by the obtained correlation value, where a greater correlation nearest to 1 indicated the highest significance. Conclusion: This research addresses a critical gap by focusing on the upper extremities in a contemporary Central Indian population. Developing stature estimation models from specific body parts not only advances anthropological research but also aids forensic investigations, especially in warm climates like Uttar Pradesh.

The Impact of Error in Persona : Lilability of Police Investigators in Wrongful Arrest Cases

Wrongful arrest in Indonesia is a serious problem in law enforcement that often results in physical suffering, psychological, and social losses for victims. One form of error that often occurs is “error in persona,” which is a misidentification that results in the arrest of an innocent person. This research uses normative juridical method with literature study and qualitative analysis to analyze the responsibility of investigators in cases of wrongful arrest. The purpose of this study is to understand the factors that cause errors in persona and their impact on victims and the legal system. The results show that misidentification often occurs due to inaccuracies in evidence collection, pressure to quickly resolve cases, and the use of inadequate investigative methods. In addition, the importance of fulfilling the legal procedures stipulated in the Criminal Procedure Code (KUHAP) is crucial to prevent these errors. Reforms in the investigation process, increased capacity of investigators, and the use of modern technology are necessary to minimize the risk of errors and ensure justice and the protection of human rights.

Investigating organised human trafficking crimes: case studies of police investigations in England

ABSTRACT Investigating organised human trafficking criminality is neither easy nor straightforward. Among the complexity is the need to balance and secure multiple, and often competing, investigative goals. Using case studies of actual human trafficking investigations in England, the present exploratory study provides insights into the tensions between safeguarding victims while also (at the same time) building up evidence against those who exploit them in order to secure a successful prosecution. Findings reveal that factors associated with the assessed level of risk of victims, the intelligence available at the start of the investigation and police resources (balanced with opportunities and risk to secure the investigative goals) influence the investigative approach followed and strategies implemented, particularly those aiming to engage with victims. The exploratory findings illustrate the importance of intelligence in risk assessment and decision-making processes during police operations, but also the need to conduct yet further research on risk assessment within the context of human trafficking investigations to inform policy and decision-making policing practices.
