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

Underlying President Bush's view regarding stemcell research and cloning are two assumptions: we originate at conception, and we have full moral status as soon as we originate. I will challenge both assumptions, argue that at least the second is mistaken, and conclude that the President's approach is unsustainable.  相似文献

1. The indications such as the place of finding, the identification of clothes or other personal items, represent only the first step towards the identification of a corpse. 2. An identification based on medical data, other than dental, is often possible, more often than it is believed. 3. The forensic pathologist plays a double role in the case of such an identification: a) in the phase of the inquiry, he must contact the investigators and the families to explain his wishes and the different possibilities of identification. b) he must use the gathered information in the appropriate way. 4. It would be desirable to compose some statistical tables of the various medical elements useful for the identification (mutilations, surgical operations, etc...). We present six cases of identification in our practice.  相似文献
