The role of the Engineer and Scientist in formulating opinions relative to evidence, which otherwise stands mute before the bar of justice, significantly affects the administration of justice. Fully qualified Engineers and Scientists, who are knowledgeable in applications of their work to legal problems, stand prepared to give voice to this otherwise mute evidence.

Recognizing that their professional disciplines have applications in investigations, law and the justice system, and that this requires distinct additional knowledge, a group of skilled and ethical engineers and scientists met together to form a professional organization in order to implement the interchange of information concerning methods, development of standards, and the furtherance of experimental research.
