Private Investigator, he wasn't a cop. He wasn't even really a PI, he was just a genius that wanted a challenge rather than live his life in a cocaine haze.
The article referenced in this thread said only investigations would be partially done by private companies. That means private investigators. Sherlock Holmes was hired on occasion by police.
And he didn't just live in a cocaine haze when not investigating, he also went for morphine, and other opiates from the local pharmacy.
