After that happened, laws were passed to make it perfectly legal to get blood from unconscious patients without a warrant (https://www.npr.org/2019/06/27/732852170/supreme-court-affirms-police-can-draw-blood-from-unconscious-drivers https://www.npr.org/2019/06/27/732852170/supreme-court-affir...) and to help avoid the problem of doctors and nurses interfering with the demands of the police, departments in several states have started training officers to draw blood from suspects themselves right on the side of the road so there's no need to take most people to a hospital. Jeff Payne, the Utah cop who was fired after his violent arrest of that nurse went viral, later got hired by the Weber County Sheriff’s Office to work in the medical unit of the county jail.
