A co-worker of mine, her husband used to work with law enforcement for cyber detective work type stuff. He was so good he was assigned a lot of hard drives and such of the kinds of content you are discussing. After about a year of it he told his boss he couldn't see any more ever it totally sickened him. They tried to give him a raise a very high raise to keep doing it because he was so good at finding it. But he told them either you assign me to something else or he quit. He just couldn't stomach it as most good people can't.
