US Homicide Rate vs US GDP (current US$)

US Homicide Rate and US GDP (current US$) correlate at r = -0.61 over 31 years (1990–2023), p = 3.1e-4. With the time trend removed, r = +0.69. Direction flips without the trend.

Verdict: Direction flips without the trend. The raw correlation is -0.61, but once each series' time trend is removed it becomes 0.69. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
