Observations of high velocity bloodspatter on adjacent objects   总被引:1,自引:0,他引:1  
In a recent homicide investigation, high velocity backspatter was observed on the sleeve cuff of the accused. These minute droplets were discovered only after microscopic examination and were limited in number. A study was initiated to determine if these were truly backspatter droplets or transferred blood produced from light contact with a bloody item. It was observed that the backspattered blood was primarily limited to contact or near contact shots. An exception was a shot into an already bloody surface. It was found that backspattered blood would deposit on the shooter's shirt sleeve irrespective of the weave pattern. Transferred blood was observed only on the fiber tops. This information was found to be useful in reconstruction of events in suicides as well as possible homicides.  相似文献

Criminal justice agencies are organized sequentially — “output” from one agency is “input” to the next — but most scholars argue that criminal justice is not a system in a theoretical sense. In this article, it is argued that general systems theory (GST) reveals important insights into criminal justice structures and functions. Specifically, it is argued that the criminal justice system processes “cases” rather than people, and that the common goal of criminal justice processing is to “close cases so that they stay closed.” It also is argued that processing capacity progressively declines, in that at each system point the subsequent agency cannot input as many cases as the previous agency can output. Each agency therefore experiences “backward pressure” to close cases in order to reduce input to the next agency. Overall, this article highlights that criminal justice agents and agencies are best understood as operating in the context of the larger whole, thus it is concluded that criminal justice is a system in the sense of general systems theory.  相似文献
