Hydrofluoric acid poisoning

A case of suicidal ingestion of hydrofluoric acid is presented. Death of the victim while in police custody was one of the more unique aspects of the case. This is the sixth case of poisoning of this type reported in Dade County. Clinical, pathological, and toxicological aspects of fluoride poisoning are discussed.     

The utility of the State-Trait Anger Expression Inventory with offenders

Self-report instruments can provide useful information as part of a thorough clinical assessment. However, their use in forensic settings can be problematic. The State-Trait Anger Expression Inventory (STAXI) has recently been proposed as an effective instrument for screening and outcome measurement in anger management programs. This study evaluated the effectiveness of this instrument in a sample of both voluntary and court-ordered anger-management clients, all of whom were determined through diagnostic interviews to have significant anger problems. Contrary to findings in nonforensic samples, the STAXI Trait Anger scale identified only about half of the participants as having anger-management problems severe enough to require intervention. Supplemental analysis with two additional scales did not significantly improve sensitivity. In addition to thorough diagnostic interviewing, forensic use of the STAXI (like similar assessment methods) may require additional validity scales to detect denial or socially desirable response patterns.     

Can you use community policing for counter terrorism? Evidence from NSW,Australia

A contested question in the international policing literature is whether it is possible to undertake effective anti-terrorism community policing. The NSW Police Force’s Counter Radicalisation Strategy involved a community engagement initiative that used community liaison officers, mostly working with Sydney Muslim communities. This study reviews the success of this initiative, drawing on data from a survey of Sydney Muslims. The community engagement initiative was found to have direct contact with the community, it was public, and it involved aspects of partnership and relations of depth. For these reasons, the initiative was within the community policing paradigm. There was strong community awareness of the programme, and a majority saw it as successful. There remained pockets of community suspicion and critique, which require attention. The respondents recommended an enhancement of the community policing aspects: more (and wider) contact, visibility and partnership. The findings affirm the utility of community policing for counter-terror work.     

Lessons learned from inter-laboratory studies of carbon isotope analysis of honey

Forensic application of carbon isotope ratio measurements of honey and honey protein to investigate the degree of adulteration with high fructose corn syrup or other C₄ plant sugars is well established. These measurements must use methods that exhibit suitable performance criteria, particularly with regard to measurement uncertainty and traceability – low levels of adulteration can only be detected by methods that result in suitably small measurement uncertainties such that differences of 1‰ or less can be reliably detected. Inter-laboratory exercises are invaluable to assess the state-of-the art of measurement capabilities of laboratories necessary to achieve such performance criteria. National and designated metrology institutes from a number of countries recently participated in an inter-laboratory assessment (CCQM-K140) of stable carbon isotope ratio determination of bulk honey. The same sample material was distributed to a number of forensic isotope analysis laboratories that could not participate directly in the metrological comparison. The results from these studies have demonstrated that the majority of participants provided isotope delta values with acceptable performance metrics; that all participants ensured traceability of their results; and that where measurement uncertainties were reported; these were fit-for-purpose. A number of the forensic laboratories only reported precision rather than full estimates of measurement uncertainty and this was the major cause of the few instances of questionable performance metrics. Reporting of standard deviations in place of measurement uncertainties is common practice outside metrology institutes and the implications for interpretations of small differences in isotopic compositions are discussed. The results have also highlighted a number of considerations that are useful for organisers of similar inter-laboratory studies in the future.     

Reluctant to embrace innocence: an experimental test of persevering culpability judgments on people’s willingness to support reintegration services for exonerees

Objectives

People are hesitant to fully support reintegration efforts (e.g., opportunities to receive psychological counseling, career counseling, job training, housing assistance, educational opportunities, financial compensation) to help exonerees wrongfully convicted of a crime. However, underlying reasons motivating people’s hesitancy remain unaddressed. This research examined the influence of being wrongfully convicted of a race stereotypic-consistent crime on people’s judgments of exonerees’ culpability and willingness to support reintegration programs.

Method

Using an experimental design, participants were randomly assigned to read a news story that depicted an African-American or White male who was exonerated after being wrongfully convicted of assault or embezzlement. Participants then offered their culpability judgments (i.e., their belief in the exoneree’s guilt and confidence in that belief) and willingness to support reintegration services.

Results

Participants were less confident of the exoneree’s innocence and less supportive of psychological counseling services when the exoneree was a White, compared to African-American, male wrongfully convicted of the race stereotypic-consistent crime of embezzlement. An exploratory conditional mediation analysis indicated that less confidence in the exoneree’s innocence after being wrongfully convicted of a race stereotypic-consistent crime was, in turn, associated with people’s hesitancy to support psychological counseling for the exoneree.

Conclusions

Basic and applied implications to overcome people’s hesitancy to support reintegration efforts for exonerees are discussed.
