One guy I talked to said occasionally they might have an attorney wanting them to do some time-consuming, heroic forensics on, say, a CD duplicator to find out how many copies of something were made. His response was something like "This guy's got pictures of a little boy getting sodomized here we're not going to drop this to work on that." Apparently there are a lot of people trading that child porn.

These forensics guys seemed to know what they're doing and had a good perspective on their priorities.
