This editorial explores theories behind falling US crime rates, challenging President Trump's supporters' claim of tough policing as the prime cause. It highlights a downtrend since the early 1990s and revisits the "Freakonomics" theory attributing a significant role to legalized abortion post-Roe v. Wade. With Roe v. Wade overturned, states now have differing abortion laws. The editorial suggests that analyzing crime data from these states over the next two decades could provide a new test for the abortion theory, emphasizing academia's long-term perspective versus politicians' demand for immediate results.
