A medical direction agreement between the Meeker County, Minnesota, Sheriff’s Office and the Hennepin County, Minnesota, Medical Center yielded an award-winning research project that has been published in a peer-reviewed scientific medical journal.1 The findings provide information to help authorities understand the physiologic interplay between common officer tactics and suspect behaviors during resistive custodial arrest situations. This understanding of physiology is important when making training, policy, and operational decisions about the safest practices during dynamic resistance situations.
