Beat patrol deployment in Hong Kong

This article addresses critical policy issues raised in the SB vs. DB debate. How should such a policy debate be resolved? What are the pros and cons of both patrol deployment measures? More importantly, what immediate and effective remedial steps can be taken to secure the front line police officers’ desire for safety and security without compromising the public's legitimate expectation for order and service. This article provides the HKP community — policymakers, operational managers and front line officers — with relevant research literature and pertinent empirical data to understand the issues involved and help resolve the debate in an informed and reflective manner. In the end, the article argues that education and training are more important than patrol deployment in reducing risk of injury to police officers in the line of duty. Removal of side arms and demilitarization of the HKP is also suggested.     

Investigation of trace inorganic elements in street doses of heroin

Sixteen trace elements found in 309 street heroin samples, piped water and contaminated water were determined using inductively coupled plasma-mass spectrometry. All the street heroin samples were found to contain high levels of sodium, a reflection of the use of sodium bicarbonate during heroin synthesis. Additionally, this element was also found to be one of the potential contaminants acquired from the piped water. Calcium could be derived from lime while iron, aluminum and zinc could have come from the metallic container used in the processing/cutting stage. The levels of these elements remained low in the heroin and it could be due to the dilution effects from the addition of adulterants. Statistical validation was performed with six links of related heroin samples using principal component analysis to find the best pretreatment for sample classification. It was obtained that normalization followed by fourth root showed promising results with 8% errors in the sample clustering. The technique was then applied to the case samples. Finally, the result suggested that the case samples could have originated from at least two major groups respectively showing unique elemental profiles at the street level.

The first international proficiency test on ketamine and norketamine in hair

This paper discusses the organization of the first international proficiency test (PT) programme on ketamine (K) and norketamine (NK) in hair samples. The primary objective of the programme was to evaluate the analytical capability of participating laboratories on hair analysis for K and NK via comparison of results. Authentic samples, instead of spiked samples were used in the programme to mimic the analysis of incorporated illicit drugs in real-life situations. Eight of the ten participating medical or forensic laboratories from Australia, France, Hong Kong, Italy, Singapore and the USA returned results to the organizer. Quantification methods from these laboratories were confined to GC-MS and LC-MS/MS. Performance assessment based on z-score indicated that only three laboratories achieved satisfactory results for both the analysis of K and NK. It was concluded that the overall performance of the participating laboratories was fair and there is still room for further improvement. Additional similarly designed PT programmes are recommended to be organized in order to encourage reliable measurements of illicit drugs in hair samples. Taking into account the substantial effect on the consensus values within limited number of data points, a recommendation on the provision of reference values assigned by accurate methods will be of benefit to small size PT programmes in the forensic field.

Youth crime and family disruption in Canadian municipalities: An adaptation of Shaw and McKay’s social disorganization theory

Using an adaptation of Shaw and McKay’s (1942) theory, the present study examined the effects of social disorganization and family disruption on youth crime. Based on data from 483 Canadian municipalities, the results revealed that low income, mobility and ethnic heterogeneity had the expected positive effects on youth crime, particularly in municipalities with smaller population and lower prevalence of low income. The effect of single parenthood was positive as expected whereas that of divorce was unexpectedly negative. The findings suggest the importance to specify the conditions for the effect of social disorganization and differentiate the effects of divorce and single parenthood. The unexpected negative effect also raises the possibility of divorce as law mobilization, thus underscoring the roles of planning and legal intervention in social disorganization. In terms of policies, the findings suggest early intervention for social disorganization, support for single-parent families, and the incorporation of divorcees in productive activities.     

Klebsiella meningitis mimicking clinical deterioration from hemorrhage of a complex posterior fossa arteriovenous malformation

We report a case of a 33-year-old male with a history of complex posterior fossa arteriovenous malformation (AVM) with partial resection done in China; at follow-up in our unit, he presented with a 1-day history of acute deterioration of consciousness level after minor head injury. The clinical and radiologic features were compatible with spontaneous hemorrhage from the AVM, and the patient died 1 day after admission. However, postmortem examination revealed the direct cause of death was due to Klebsiella meningitis. The clinical catch is highlighted, and the importance of early and prompt detection of this condition is emphasized.     

Treatment of Gang Members Can Reduce Recidivism and Institutional Misconduct

Gang violence creates serious safety and security concerns in the community and prisons. Treated gang and nongang members recidivated significantly less in a 24-month follow-up than their untreated matched controls. Treatment consisted of high intensity cognitive-behavioral programs that follow the risk, need, and responsivity principles (Andrews & Bonta, 2003). The treated gang members who recidivated violently after treatment received significantly shorter sentences (i.e. they committed less serious offences) than their untreated matched controls. Untreated gang members had significantly higher rates of major (but not minor) institutional offences than the other three groups. Correctional treatment that follows the risk, need and responsivity principles appears able to reduce recidivism and major institutional misconduct. Effective correctional treatment should be considered as one of the approaches in the management and rehabilitation of incarcerated gang members.     

Reintegrating seriously violent and personality-disordered offenders from a supermaximum security institution into the general offender population

Offenders who have committed serious violent acts while incarcerated are often segregated and housed in supermaximum security facilities. Given the highly restricted regime under which they are detained, it is often difficult to decide if they are safe enough to be discharged. However, there is a need to reintegrate them into the general offender population in a lower security institution for humane, correctional, and financial reasons. We propose a transitional strategy to facilitate their reintegration by way of a maximum-security step-down treatment-oriented facility within which both their security requirements and treatment needs could be adequately met. The present study reports the results of such an approach. More than 80% of the offenders (n = 31) were reintegrated into a lower-security facility without relapsing and being returned to the supermaximum institutions within a follow-up period of 20 months. They also have lower institutional offense rate postreintegration compared to prereintegration.
