Testing the “Law of Crime Concentration at Place” in a Suburban Setting: Implications for Research and Practice

Objective

To assess whether the “law of crime concentration at place” applies in a non-urban context. We test whether longitudinal trends in crime concentration, stability, and variability apply in a suburban setting.

Methods

We use group-based trajectory analysis to examine trends in recorded crime incidents on street segments in Brooklyn Park, a suburban city outside Minneapolis, Minnesota, over a 15-year period from 2000 to 2014.

Results

Consistent with the law of crime concentration at place, crime in Brooklyn Park is highly concentrated at a small percentage of micro-places. Two percent of street segments produced 50 % of the crime over the study period and 0.4 % of segments produced 25 % of the crime. The patterns of concentration are highly stable over time. However, the concentration of crime is substantially higher and there is much less street-by-street variability in Brooklyn Park compared to urban areas.

Conclusions

We find strong support for the application of the law of crime concentration at place to a non-urban setting, suggesting that place-based policing approaches tested in cities can also be applied to suburbs. However, there are also important differences in the concentration and variability of crime hot spots in suburbs that require further examination. Our study is based on a single setting that may not be representative of other suburban and rural areas. Finally, the clustering of hot spots raises questions about the use of street segments to analyze crime at suburban micro-places.

     

Spatio-Temporal Change of Crime at Provincial Scale in China—Since the Economic Reform

China has undergone tremendous social changes during the transition since the Economic Reform, and this paper did a comparative study on crime change patterns among provinces both spatially and temporally. The results indicated that (1) regional differences on crime levels and temporal change trends were largely influenced, or even been shaped, by the outcomes brought by economic reform, such as priority developmental policies, geographical location, transportation facilities, etc. For example, spatially, more developed areas with more governmental policy supports not only saw dramatic development during the economic reform but also showed higher criminal rates and greater criminal rate variation. (2) The relationships between criminal rates and corresponding contextual conditions vary by temporal scales (long-run and short-run), regions, target areas’ features and their different development policy priorities; (3) experiences from Western theories and empirical studies cannot be applied directly into the Chinese society, without taking into consideration of the spatial-temporal scales and target’s specialities; it is also suggestive to local policy-makers and governmental agencies that crime reduction and prevention measures should not be identical to other places and need to be made according to local characteristics.     

Examining the Relationship Between the Structural Characteristics of Place and Crime by Imputing Census Block Data in Street Segments: Is the Pain Worth the Gain?

Objective

The current study proposes unique methods for apportioning existing census data in blocks to street segments and examines the effects of structural characteristics of street segments on crime. Also, this study tests if the effects of structural characteristics of street segments are similar with or distinct from those of blocks.

Methods

This study compiled a unique dataset in which block-level structural characteristics are apportioned to street segments utilizing the 2010 U.S. Census data of the cities of Anaheim, Santa Ana, and Huntington Beach in Orange County, California. Negative binomial regression models predicting crime that include measures of social disorganization and criminal opportunities in street segments and blocks were estimated.

Results

The results show that whereas some of the coefficients tested at the street segment level are similar to those aggregated to blocks, a few were quite different (most notably, racial/ethnic heterogeneity). Additional analyses confirm that the imputation methods are generally valid compared to data actually collected at the street segment level.

Conclusions

The results from the street segment models suggest that the structural characteristics from social disorganization and criminal opportunities theories at street segments may operate as crucial settings for crime. Also the results indicate that structural characteristics have generally similar effects on crime in street segments and blocks, yet have some distinct effects at the street segment level that may not be observable when looking at the block level. Such differences underscore the necessity of serious consideration of the issues of level of aggregation and unit of analysis when examining the structural characteristics-crime nexus.

     

Not Afraid at All? Dominant and Alternative Interpretative Repertoires in Discourses of the Elderly on Fear of Crime

This article demonstrates how a dominant and an alternative interpretative repertoire are activated and negotiated within two focus group discussions conducted with elderly people around the issue of fear of crime: the active, competent actor and the potential victim. In contrast to quantitative generalist studies that tend to neglect the ambiguity and complexity of group membership and identification, a contextualized, dynamic, and interactive understanding of the elderly – as well as of the victim – identity is presented.     

When Love is a Crime: Is the Criminalisation of Same Sex Relations in Nigeria a Protection of Nigerian Culture?

Even though studies suggest that people do not have a choice about their sexual orientation since it is innate in them, some African countries including Nigeria continue to criminalise same sex conduct between two consenting adults. Before the administration of President Goodluck Jonathan passed the Same Sex Marriage (Prohibition) Act 2014 into law in Nigeria, there have already been laws in the country criminalising sexual relations between persons of the same sex. It appears that the Act of 2014 was motivated to show a resolve by the Nigerian government to clearly point out to certain sections of the international community, who at that time were lobbying for the decriminalisation of same sex relations in the country, that there was no intention by the Nigerian state to cave into any such demand. This paper re-examines the prohibition of same sex relations in Nigeria with a focus on whether the laws protect the culture of the Nigerian people or the moral ideals introduced by religion.

Is it Important to Examine Crime Trends at a Local “Micro” Level?: A Longitudinal Analysis of Street to Street Variability in Crime Trajectories

Over the last 40 years, the question of how crime varies across places has gotten greater attention. At the same time, as data and computing power have increased, the definition of a ‘place’ has shifted farther down the geographic cone of resolution. This has led many researchers to consider places as small as single addresses, group of addresses, face blocks or street blocks. Both cross-sectional and longitudinal studies of the spatial distribution of crime have consistently found crime is strongly concentrated at a small group of ‘micro’ places. Recent longitudinal studies have also revealed crime concentration across micro places is relatively stable over time. A major question that has not been answered in prior research is the degree of block to block variability at this local ‘micro’ level for all crime. To answer this question, we examine both temporal and spatial variation in crime across street blocks in the city of Seattle Washington. This is accomplished by applying trajectory analysis to establish groups of places that follow similar crime trajectories over 16 years. Then, using quantitative spatial statistics, we establish whether streets having the same temporal trajectory are collocated spatially or whether there is street to street variation in the temporal patterns of crime. In a surprising number of cases we find that individual street segments have trajectories which are unrelated to their immediately adjacent streets. This finding of heterogeneity suggests it may be particularly important to examine crime trends at very local geographic levels. At a policy level, our research reinforces the importance of initiatives like ‘hot spots policing’ which address specific streets within relatively small areas.     

The Roots of Modern White-Collar Crime: Does the Modern Form of White-Collar Crime have its Foundation in the Transition from a Society Dominated by Agriculture to One Dominated by Industry?

The purpose of the present paper is to investigate whether the process of transition from an agricultural to an industrial society was a watershed for white-collar crime, such that this type of crime increased rapidly in connection with the industrialization process. The theoretical reasoning behind this notion is that the transition process promoted a mentality characterized by self-centered values and a culture of competitiveness, which together paved the way for fraud perpetrated at the expense of others. The data are from Statistic Sweden’s historical records and cover the period of 1864–1912. Since there is no way to measure all crimes that can be defined as white collar crime, we have used bankruptcy offences as an example of white collar crime. The results do not support the notion that the transition period from an agricultural to an industrial society showed an increase in bankruptcy offences. Instead, the results show that when fluctuations in the economy are taken into account, the industrialization process per se entailed less bankruptcy offences. On the other hand, other research using the case of Sweden has shown that it was first after World War II that bankruptcy offences increased rapidly. Our argument is that the transition process as a structural mechanism had a greater impact on bankruptcy offences when industrialized capitalism became advanced.

Alteration of the Death Scene After Self‐stabbing: A Case of Sharp Force Suicide Disguised by the Victim as a Homicide?

This paper reports a case of a 72‐year‐old woman who was found dead in her bedroom with a 4 cm vertical stab wound in the abdomen. A bloodstained knife was found in the top drawer of her bedside table. The clothes worn by the victim showed no damage. A bloodstained vest and a sweater with frontal incisions were found far from the victim, in the bathroom and in the bedroom respectively. Several bloodstains were found in every room of the apartment. The evidence found during the forensic examination and, in particular, the Bloodstain Pattern Analysis, led the investigators to determine the manner of death, being consistent with a suicide with a long‐lasting physical activity after self‐stabbing. This report describes an unusual case of “disguised suicide,” in which the victim tried to cover‐up the suicide by changing her clothes and concealing the weapon, in the last minutes of her life.     

Could Innovations in Policing have Contributed to the New York City Crime Drop even in a Period of Declining Police Strength?: The Case of Stop,Question and Frisk as a Hot Spots Policing Strategy

Available data make it impossible to reach strong conclusions about the role of policing in the New York crime decline. Instead, we examine whether innovations implemented in New York fit with what is known about effective policing strategies. Our main analysis focuses on how the New York City Police Department (NYPD) could have continued to contribute to the crime drop over the last decade when the number of police declined significantly. We examine geographic data on crime and stop, question and frisks (SQFs) to show that SQFs are concentrated at crime hot spots. We also show that the NYPD increased these specific hot spots policing strategies despite declining numbers. In our discussion, we speculate on whether this “doing more with less” could be an explanation for the continued crime drop in New York, noting the limitations of drawing conclusions from existing data. We also raise concerns about possible backfire effects of SQF hot spots approaches.     

Justice at risk! An evaluation of a pseudoscientific analysis of a witness’ nonverbal behavior in the courtroom

Psychology and law have developed as disciplines through rigorous data collection, exploration and analysis, and the publication of findings through peer-review processes. Such findings are then used to implement evidence-based practices within a variety of settings. However, in parallel to factually and scientifically based knowledge, ‘alternative’ science, or pseudoscience, has gained in popularity. The present case study aims to evaluate the empirical evidence and theoretical underpinnings of a publically accessible analysis of a suspected serial killer’s nonverbal behavior during a bond hearing published online by two ‘synergologists’. The case study emphasizes how a ‘synergological’ analysis to understanding and interpreting human behavior fails to use empirical data, making generalized inferences based on erroneous assumptions. The case study also highlights the detrimental effects such assumptions may have within the justice system and why pseudoscientific analytical approaches should be vigorously challenged by research scientists.     

Changing Typology of Organised Crime in a Post-Socialist Lithuania (the Late 1980s–Early 2000s)

This paper analyzes the dynamics of organised crime in post-socialist Lithuania. Three overlapping periods in evolution of organised crime are discerned. During the mid 1980s organised crime emerged with the attempts to liberalise the state socialism by legalizing cooperative and individual property as a basis for economic activities. By the early 1990s organised crime in Lithuania began to metamorphose from illegal manufacturing to opportunistic criminality associated with the privatisation of state property. Since the mid 1990s organised crime has again undergone change. It has entered what could be termed a maturation phase. This maturation was influenced by a number of factors including; the end of the privatization process, resumed growth of the economy, development of the legal and fiscal infrastructure to regulate a market economy, and increasing effectiveness and successes of policing in Lithuania [1] [1] Johnstone, Peter 2005. ‘Commissar-General Vytautas Grigaravièius, Lithuania national police’. Police Practice and Research, 5(4–5), September–December, pp. 357–370. . In this article the political, socio-economic, organisational and cultural factors that influenced the dynamics of change in organised crime are analyzed.     

Was elusive carnivore a panther? DNA typing of faeces reveals the mystery

In this study, we report the findings of a recent case in which the officials of an Indian zoo claimed that an animal, possibly a carnivore, is periodically visiting the zoo from a nearby vast forest area and causing panic in zoo and nearby villages. They collected some elusive faecal material from the vicinity of an herbivore enclosure. Looking to the pugmarks found in that area and faecal matter ceased, the officials could not decide whether it was a lioness, a tiger or a panther. We resolved this mystery by DNA-based analysis of the faecal material, using our recently developed novel universal primers to amplify and sequence a specific fragment of mitochondrial cytochrome b gene. The findings of the DNA-based analyses were confirmed after few days when the zoo officials trapped the animal of same species as suggested in our report. The potential of our procedure to investigate the cases related to wildlife offence is discussed.     

The Issue of Age Estimation in a Modern Skeletal Population: Are Even the More Modern Current Aging Methods Satisfactory for the Elderly?,

The main idea behind age assessment in adults is related to the analysis of the physiological degeneration of particular skeletal structures with age. The main issues with these procedures are due to the fact that they have not been tested on different modern populations and in different taphonomic contexts and that they tend to underestimate the age of older individuals. The purpose of this study was to test the applicability and the reliability of these methods on a contemporary population of skeletal remains of 145 elderly individuals of known sex and age. The results show that, due to taphonomic influences, some skeletal sites showed a lower survival. Therefore, the methods with the highest percentage of applicability were Lovejoy (89.6%) and Rougé‐Maillart (81.3%), followed by Suchey‐Brooks (59.3%), and those with the lowest percentage of applicability were Beauthier (26.2%) and Iscan (22.7%). In addition, this research has shown how for older adults the study of both acetabulum and auricular surface may be more reliable for aging. This is also in accordance with the fact that auricular surface and the acetabulum are the areas more frequently surviving taphonomic insult.     

The use of the M-Vac® wet-vacuum system as a method for DNA recovery

Collecting sufficient template DNA from a crime scene sample is often challenging, especially with low quantity samples such as touch DNA (tDNA). Traditional DNA collection methods such as double swabbing have limitations, in particular when used on certain substrates which can be found at crime scenes, thus a better collection method is advantageous. Here, the effectiveness of the M-Vac® Wet-Vacuum System is evaluated as a method for DNA recovery on tiles and bricks. It was found that the M-Vac® recovered 75% more DNA than double swabbing on bricks. However, double swabbing collected significantly more DNA than the M-Vac® on tiles. Additionally, it was found that cell-free DNA is lost in the filtration step of M-Vac® collection. In terms of peak height and number of true alleles detected, no significant difference was found between the DNA profiles obtained through M-Vac® collection versus double swabbing of tDNA depositions from 12 volunteers on bricks. The results demonstrate that the M-Vac® has potential for DNA collection from porous surfaces such as bricks, but that alterations to the filter apparatus would be beneficial to increase the amount of genetic material collected for subsequent DNA profiling. These results are anticipated to be a starting point to validate the M-Vac® as a DNA collection device, providing an alternative method when DNA is present on a difficult substrate, or if traditional DNA collection methods have failed.     

How Much Time Should the Police Spend at Crime Hot Spots? Answers from a Police Agency Directed Randomized Field Trial in Sacramento,California

Hot spots policing has been shown to be an effective strategy for reducing crime across a number of rigorous evaluations, but despite this strong body of research, there still exist gaps in our knowledge of how officers can best respond to hot spots. We report on a randomized experiment in Sacramento, California that begins to address these gaps by testing the recommendation from prior research that police officers randomly rotate between hot spots, spending about 15?min patrolling in each. Our results suggest significant overall declines in both calls for service and crime incidents in the treatment hot spots relative to the controls. Additionally, the study was carried out primarily by the Sacramento Police Department without any outside funding. In an era of limited economic resources for policing, this experiment suggests a model by which police agencies can take ownership of science and oversee the implementation and evaluation of evidence-based interventions.     

Is it to the advantage of a defendant to infer a greater number of contributors to a questioned sample than is necessary to explain the observed DNA profile?

When a forensic scientist presents the results of a comparison between a DNA profile from a questioned sample with that of a defendant the interpretation will be based on the premise of a given number of contributors. It is quite common practice for defence counsel to ask how consideration of a greater number of putative contributors to the profile would affect the interpretation. This note discusses the response to such a request.
