The introduction of scanning electron microscopy and energy dispersive x-ray analysis to forensic science has provided additional methods by which investigative evidence can be analyzed. The importance of evidence from the scene of a crime or from the personal belongings of a victim and suspect has resulted in the development and evaluation of SEM/x-ray analysis applications to various types of forensic evidence. The intent of this paper is to describe some of these applications and to relate their importance to the investigation of criminal cases.The depth of field and high resolution of the SEM are an asset to the evaluation of evidence with respect to surface phenomena and physical matches (1). Fig. 1 shows a Phillips screw which has been reconstructed after the head and shank were separated during a hit-and-run accident.

Surface Changes

Sufficient experience has been gained during the past five years to suggest an extended application of microreplication and scanning electron microscopy to problems of forensic science. The author's research was originally initiated with a view to develop a non-destructive method for identification of materials that went into objects of art, notably ivory and ivories. This was followed by a very specific application to the identification and duplication of the kinds of materials from animal teeth and tusks which two centuries ago went into the fabrication of the ivory dentures of George Washington. Subsequently it became apparent that a similar method of microreplication and SEM examination offered promise for a whole series of problems pertinent to art, technology and science. Furthermore, what began primarily as an application to solid substances has turned out to be similarly applicable to soft tissue surfaces such as mucous membranes and skin, even in cases of acute, chronic and precancerous epithelial surface changes, and to post-mortem identification of specific structures pertinent to forensic science.

The article examines the key provisions of traditional and developing branches of forensic technology as a branch of the forensic science. The article analyzes modern publications of domestic and foreign scientists dedicated to the problems of forensic technology. Discussion issues and gaps existing in the theory and practice of such branches of forensic technology as forensic photography and video recording, forensic phonoscopy, forensic traceology, forensic weapons science, forensic documentation, forensic research of substances, materials and products, forensic registration, etc. The opinions of individual forensic scientists on the resolution of controversial issues of forensic technology are given. The scientific directions that have not received at present recognition of independent branches of forensic technology are indicated. The promising areas of research in the framework of the branches of forensic technology are named, the main trends of its further development are formulated.

Scene Investigation

The CSI Effect posits that exposure to television programs that portray forensic science (e.g., CSI: Crime Scene Investigation) can change the way jurors evaluate forensic evidence. The most commonly researched hypothesis under the CSI Effect suggests that shows like CSI depict an unrealistically high standard of forensic science and thus unreasonably inflate the expectations of jurors. Jurors are thus more likely to vote to acquit, and prosecutors face higher burden of proof. We review (1) the theory behind the CSI Effect, (2) the perception of the effect among legal actors, (3) the academic treatment of the effect, and (4) how courts have dealt with the effect. We demonstrate that while legal actors do see the CSI Effect as a serious issue, there is virtually no empirical evidence suggesting it is a real phenomenon. Moreover, many of the remedies employed by courts may do no more than introduce bias into juror decision making or even trigger the CSI Effect when it would not normally occur (i.e., the self-fulfilling prophesy). We end with suggestions for the proper treatment of the CSI Effect in courts, and directions for future scholarly work.

We do not know how often false positive reports are made in a range of forensic science disciplines. In the absence of this information it is important to understand the naive beliefs held by potential jurors about forensic science evidence reliability. It is these beliefs that will shape evaluations at trial. This descriptive study adds to our knowledge about naive beliefs by: 1) measuring jury-eligible (lay) perceptions of reliability for the largest range of forensic science disciplines to date, over three waves of data collection between 2011 and 2016 (n = 674); 2) calibrating reliability ratings with false positive report estimates; and 3) comparing lay reliability estimates with those of an opportunity sample of forensic practitioners (n = 53). Overall the data suggest that both jury-eligible participants and practitioners consider forensic evidence highly reliable. When compared to best or plausible estimates of reliability and error in the forensic sciences these views appear to overestimate reliability and underestimate the frequency of false positive errors. This result highlights the importance of collecting and disseminating empirically derived estimates of false positive error rates to ensure that practitioners and potential jurors have a realistic impression of the value of forensic science evidence.
