Counterevidence of crime-reduction effects from federal grants of military equipment to local police.

In 2017, the Trump Administration restored local law enforcement agencies' access to military weapons and some other types of surplus military equipment (SME) that had been prohibited by the Obama Administration. The Justice Department background paper used to justify this decision cited two papers published by the American Economic Association. These papers used SME data collected with a 2014 Freedom of Information Act request and concluded that SME, supplied to local law enforcement by the federal government via the 1033 Program, reduces crime.
