I've done various forensic-oriented gigs for court cases. I was always given an titles like "Technical Expert" and sometimes really specific "Expert" terminology. In one case I was brought in only to give a high level synopsis about how deleted files can often be carved out either in full or in part, may appear in multiple places at once, sometimes clearly showing edits, and also come with useful metadata stored within the directory entries both past and present. They referred to me as the "Computer Filesystem Expert" which I thought was a bit strange, because I'm not what I'd consider an expert in file systems. Hell, I only barely know how journaling works without breaking down. I just know a lot about a very specific set of details that are useful in a forensic investigation. So there is yet another use of the word "expert" that doesn't necessarily mean the same thing to everyone. It's not a useless title in this case, but it's really ambiguous to a person who understands more than the role requires.
