An important component of crime scene reconstruction is bloodstain pattern analysis (BPA). Where BPA concerns impact patterns, estimating the area of origin is critical information for scene reconstruction. Traditionally, this is achieved by measuring individual bloodstains and performing trigonometric calculations; however, 3D scanning has been proposed as a viable alternative for overcoming logistical and practical concerns with the manual method. Therefore, this project aimed to establish whether the FARO Focus 3D scanner and FARO Zone 3D software can improve the accuracy of area of origin estimates relative to the manual method. We created a series of eight bloodstain impact patterns and performed paired analysis using the two methods to estimate areas of origin for each pattern. Our data suggested that FARO-derived estimates were generally more accurate than using the manual method. FARO-estimated heights of origin areas were generally closer to the true distance. Both methods underestimated the distance from the wall for most patterns originating 150mm or greater from the wall, but overestimated distances for patterns originating closer to the wall. The degree to which distances were underestimated increased significantly the further the blood source was from the wall and was greater for FARO-derived estimates. The results of this research contribute to the validation of these instruments for operational implementation for BPA and should be considered alongside the practical benefits of 3D scanning relative to manual methods. Further, 3D scanning can provide reliable BPA reconstruction documentation for technical review and court presentation. 相似文献

In recent years, legislators in all fifty states have given grandparents rights to petition for visitation privileges with grandchildren that can be enforced over parental objections. Grandparent visitation rights reflect an effort to protect meaningful relationships children enjoy with nonparental caregivers, enlist the assistance of extended family when the child's nuclear family is disrupted, and defend the interests of grandparents themselves. This psycholegal analysis explores the direct and indirect consequences of grandparent visitation statutes for family functioning. Statutory provisions are summarized, and the effects of these statutes are evaluated in light of what is known about the role of grandparents in child development, how courts evaluate children's "best interests" in grandparent visitation disputes, and how these statutes can alter family functioning in informal ways. The authors conclude that there are risks as well as benefits to children and families in grandparent visitation statutes, and suggest directions for procedural and statutory reform. 相似文献

On January 1, 1996, a new law took effect in Texas granting certain state citizens the privilege to carry a concealed handgun
on their person for the first time since 1871. As a result of this dramatic shift in state law, Texas is now among the growing
number of states across the nation who have adopted similar statutory provisions in one form or another. While at least one
empiricals study of citizen’s attitudes toward concealed handgun ownership was conducted prior to the law’s effective date,
no similar efforts were undertakens to assess the beliefs, perceptions and attitudes of the state’s law enforcement officers
about this important social policy. The present study was therefore undertaken in response to the lack of serious attention
which the issue of concealed handgun ownership among private citizens has received as it directly relates to the law enforcement
profession. Subjects for this study (N=327) were drawn from four Texas law enforcement agencies representing various organizational
sizes and missions. While the responses of officers who participated in the study indicate optimism about the law’s potential
to deter various types of crime, they also reflect a certain degree of concerns about concealed handgun ownership among private
citizens especially as this policy directly relates to perceive inadequacies in statemandated requirements and issues affecting
officer safety. 相似文献
