At the GOP midterm convention in Dallas, President Trump claimed he had reversed a crime wave that had occurred under President Biden. The specific crime data expert who rebutted the claim:

THE CORRECTION
Crime data expert Jeff Asher stated directly: ‘No, crime began dropping significantly in 2023 during the Biden administration. Murder fell at record rates in 2023, 2024 and 2025. Violent crime also declined nationally in 2023 and 2024.’
Jeff Asher is a crime data analyst who tracks public safety statistics as his specific professional expertise. His statement is a specific, sourced, factual correction to a specific factual claim. ONYX covers it at that level.
THE SPECIFIC DOCUMENTED FACTS
▸ Murder fell at record rates in 2023 and 2024 — during the Biden administration
▸ Violent crime declined nationally in 2023 and 2024 — during the Biden administration
▸ 2025 data shows continued crime decline — which the Trump administration can accurately credit
▸ The claim that there was a Biden-era crime wave that Trump reversed is not consistent with the documented crime data
WHY DATA ACCURACY MATTERS
Crime statistics directly affect public policy decisions: policing strategies, incarceration policy, prosecutorial priorities, and community investment decisions are all made based on crime trend data. If the public believes crime rose under Biden and was reversed under Trump when the documented trend shows the opposite, policy decisions made on that belief are being made on a false factual foundation. ONYX covers the correction because accurate public information about crime trends is a specific public good.
Crime began dropping significantly in 2023. Under Biden. Murder fell at record rates in 2023, 2024, and 2025. The crime data expert said so, directly, using those specific words. That is the documented factual record.
