"Information broker. I gather the information, people pay me for it."

While it has some similarities to what detectives do, there's a lot less justice involved. Detectives usually do more talking to people. And with a lot of what he gathers, it's not immediately related to an open inquiry someone came to him about. It's related instead to staying aware of current events, analyzing recurring details to predict something's next time and location of appearance, and anything that strikes his whim. Like that time he dug up records of tough players and hunted down someone who hadn't logged in in ten years just to play someone with an unbeaten record.

The device gives a few more seconds before finally accepting that answer and moving on to the next sin that it types up.
