The causation of suicidality is multi-dimensional, however, there are insufficient studies which have examined the burden and risk factors of suicidality in Nigerian police officers. Objective: To determine the prevalence and predictors of suicidality among police officers in Lagos, Nigeria. Methods: This was a cross-sectional study of 600 police officers who were selected using a non-probability sampling method. Questionnaires used were: Suicide Behaviour Questionnaire-Revised (SBQ-R), State-Trait Anxiety Inventory (STAI), and a Socio-Demographic Questionnaire. Results: Prevalence of suicidality was 14%, and the predictors of suicidality were: state anxiety (p 0.001), trait anxiety (p 0.001), substance use (p = 0.03), being unmarried (p = 0.03), and female gender (p = 0.02). Conclusion: Suicidality is prevalent among Nigerian police officers, with a higher risk in those who are vulnerable. The creation of government policies and infrastructure which promote mental health in police officers is necessary.展开更多

This study discussed definition of cybercrime, cybercrime categories as well as comparison between traditional criminal techniques and cybercrime. As the abilities and skills required for detectives to investigate cybercrime have been discussed. Additionally, literature review and related work, was addressed challenges role of the police in combating cybercrime and facing cybercrime policing. We proposed the main tool in the study which is “Checklist of essential skills for a cybercrime investigator”. Thus, to gain the ability to Identify technical and practical requirements in terms of skills, programs, and equipment to achieve effective and professional results in fight cybercrimes.展开更多

The objective of this article is to detail the police commitment procedure in England and Wales, as dictated by the mental health act of 1983 (MHA 1983) amended in 2007 (MHA 2007);and compare this with similar legal provisions as prevails under current state mental health statutes in the United States of America (USA). The comparative review of the commitment processes in England and Wales to that of the USA reveals that the process in England and Wales seeks to primarily ensure that persons with mental disorder (PWMD) in crisis are directed to a specialist hospital for evaluation and appropriate specialist care. In the USA such persons in a good number of cases may end up in the criminal justice system due to application of the “dangerousness” standard. Additionally whereas in England and Wales the commitment law is uniform in law and application, the federal system in the USA is such that the commitment law may have minor variations depending on the individual states. The minor variation in state commitment laws may engender a situation where the commitment law in England and Wales may seem relatively equitable and just towards PWMD in crisis, compared to the state commitment laws in the USA.展开更多

The database also revealed that the number of property crimes reported in this country has always exceeded the number of violent crimes. Although in 2013, crimes related to property are higher （117,687） than violent crime （29,375）, the gradual increase in the latter does worry Malaysians. Likewise, Malaysian Government had implemented a ＂safe community＂ concept, inspired by the Malaysian Crime Prevention Foundation （MCPF）, a non-government organization, as they were concerned that the threat of violent crime and non-violent crime would eventually reduce the quality of life for many individuals. The concept is very important to the public as it is perceived as improved safety for the public with less crime. This study analyzes the public safety through their perceptions on the effectiveness of the policeman and suggesting few prevention actions against crime. The data were collected using a self-administered survey questionnaire. Specifically, this study focuses on the more developed states in this country. From the cross tabulation analysis, the majority of respondents agreed that the police are effective in controlling crime. Approximately, 72.1% of respondents felt that the police are efficient in controlling crime.展开更多
