Fatal and nonfatal shootings by police are a public health issue that warrants additional research. Prior research has documented associations between fatal shootings by police and gun ownership, legislative strength scores, and lax concealed carry weapons laws. Despite research on other firearm-related outcomes, little is known about the impact of permit-to-purchase (PTP) laws on shootings by police. We generated counts of fatal and nonfatal OIS from the Gun Violence Archive from 2015 to 2020. We conducted cross-sectional regression modeling with a Poisson distribution and robust standard errors. In addition to PTP, we included several state-level policies that may be associated with shootings by police: comprehensive background check only (CBC-only) laws, concealed carry licensing laws, stand your ground laws, violent misdemeanor prohibitions, and extreme risk protection orders (ERPO). We controlled for state-level demographic characteristics and included a population offset to generate incidence rate ratios (IRR).
