Preliminary data from the Major Cities Chiefs Association shows a significant decline in violent crime across major U.S. cities in the first half of 2024 compared to 2023, with a 17% reduction in homicides and a 6% overall drop in violent crime. Washington D.C. and Atlanta both reported substantial decreases in various crime categories, contradicting claims by former President Donald Trump about rampant crime. The data suggests that federal, state, and local efforts to combat crime, such as hiring more police and disrupting violent drug trafficking, may be contributing to this trend. Cities like San Francisco, Oakland, and Austin also saw notable declines, although some cities, like Omaha, experienced increases in certain categories like homicides. These findings come as crime remains a key political issue in the run-up to the 2024 election, with Republicans continuing to emphasize crime rates in their campaigns.
