RT Article T1 Neck-restraint bans, law enforcement officer unions, and police killings JF Criminology & public policy VO 23 IS 3 SP 663 OP 688 A1 Beck, Brenden A2 Antonelli, Joseph A2 LaScala-Gruenewald, Angela LA English YR 2024 UL https://krimdok.uni-tuebingen.de/Record/1902414888 AB Research Summary Following high-profile police killings, many U.S. cities banned officers from using chokeholds and other neck restraints. The evidence for such bans, however, is limited. To test whether use-of-force policies prohibiting neck restraints are related to fewer police killings, we use three modeling approaches to analyze 2183 U.S. cities between 2009 and 2021. Police killings were lower in places that adopted neck-restraint bans and the bans were associated with less crime and fewer assaults on officers, net of controls. Because officer labor unions can affect use-of-force policies and the frequency of police killings, we also analyzed them, finding unionization increased the likelihood a city had a neck-restraint ban and had a null or negative association with police killings. Policy Implications Adopting a neck-restraint ban is likely an effective way to reduce deaths due to police use of force with minimal collateral consequences. The bans operate through a diffuse discouragement of many types of lethal force or as a part of an array of use-of-force policies. Their direct relationship to asphyxiation deaths remains unclear. Officer unionization is unlikely to change the frequency of police killings, except through its association with stricter use-of-force policies.
