I had worked this location before as an undercover narcotics officer on a motorcycle. It wasn’t difficult to find people selling marijuana, LSD, or heroin. Overdoses weren’t all that uncommon in the park. Neither were gang rapes. It was the early 1970s, and the drug culture was in full swing, with violent crime and property crime soaring nearly fivefold in the past ten years. People from my age group were self-destructing every day.
