Technological Advancements In Crime Scene Investigation
Abstract
Ever since there has been crime there has been Crime Scene Investigations (CSI). Throughout the 1900’s and continuing into current day, technological advancements in CSI have been taken for granted. In the past, law enforcement (LE) agencies and investigators were not capable of having regular access to the tremendous amount of information that can be found and analyzed from a crime scene. Present days CSIs typical “tools of the trade” range from flat out boring every day devices to the technologically astonishing, but overall they have all greatly impacted how evidence is collected, documented, and evaluated.
Modern technological advancements such as DNA analysis or image enhancement have made forensic investigations much easier. …show more content…
Panoramic photography, two-dimensional (2D) and three-dimensional (3D) imaging used to document crime scenes can include traditional still photography, videography, panoramic photographic imaging, and multidimensional laser scanners.
For more than 100 years, photography has been an effective means in the CSI process, with specialized applications for firearms, fingerprints, and ultraviolet photography for bloody shoe prints being introduced as early as 1902 (Buckles, 2007). With the advancement of photography from black and white media of the 1940s to digital imaging, the admissibility of digital photos in the courts was challenged in the mid-1990s and involved several high profile and landmarked cases, including State of Washington vs. Eric Hayden (1995) and State of California vs. Philip Lee Jackson (1995). In both these cases, photography in digital format was accepted and pivotal to the final decision of the court. Panoramic …show more content…
Other advances on the horizon for the CODIS is the wide spread implementation of the CODIS database with not only all the Unites States but with the well-developed convicted felon database possessed by Great Britain (Learner, 2009). Along with the database expansion CODIS users will soon see an increase in automated procedures and the use of computer analysis. While these approaches will save time, they are not expected to replace human judgment in the final review of data, but will overall cut costs considerably (Learner,
