There are many types of evidence that an officer can gather out on the scene. But all evidence is not created equal. Photographs, for example, are often used to help a jury see the scene from the photographer's point of view. But these pictures contain limited and often one-sided points of view, so criminal prosecutors started to prefer video evidence over the standard still image.
But video evidence has significant evidentiary limitations, especially in post-incident reconstruction cases. Video images are displayed in 2D (two dimensions), making it difficult to determine the distance and heights of objects and people. Video images, just like still pictures, only show a one sided-point of view – the videographers.
Prosecutors looked for a better alternative to photographs and video and found 3D laser scanners. The best form of visual display evidence comes from advanced laser scanner systems. Laser scanners are powerful tools that capture the finest details of crime scenes that traditional photographs and videos may leave out.
