Relatedly, I had a co-worker who&#x27;d once worked for the Washington, D.C. Metropolitan Police Department doing data entry.  He frequently had to review images or video footage (not all of which was produced by police, but sometimes collected as evidence) and classify it before entering it into their database.  He didn&#x27;t last long, only a few months before he quit, and he said that 10 years later he still sometimes had nightmares about the things he saw while on the job.
