Myth of the Day

Qualifying a witness as an expert in digital forensics means the witness is an expert in computers.
Category: All DME Myths
The act of endorsing a witness as an expert is a legal designation intended to benefit the trier of fact. There are many facets to the definition of “expert witness.” The witness may have little control over the adjective used in conjunction with “expert” and the specific term chosen by a non-technical court officer (e.g., attorney) does not necessarily dictate what that witness knows or is willing to present. Further, the specific terms “digital forensics” or “computer forensics” may imply to the non-technical person that they mean an expertise in all things dealing with computers. However, these terms actually refer to a sub-discipline of digital and multimedia forensics that involves the scientific examination, analysis, and/or evaluation of digital/multimedia evidence in matters of possible legal consequence.
