I would like to call your attention to this very well documented article on Scanning for Forensic Criminal Defense Presentations. This first appeared in Landair Surveying News, which offers a number of impressive, hands-on case studies.
The article includes a number of references to the use of laser scanned data in the courtroom, as well as information on costs and insights into how the technology is being applied.
One forensic expert was quoted as saying, To my knowledge no laser scanner data properly presented has ever been ruled inadmissible in any court in the United States. In fact many police departments and federal agencies use scanners to collect evidence for all types of criminal and civil investigations.
