“Tyre Nichols was a 29-year-old man who died on January 10, 2023, three days after a traffic stop by five Memphis Police Department officers. According to the Tennessee Bureau of Investigation (TBI), he was stopped on January 7 for reckless driving, ran from an encounter with police and then had another. After he complained of shortness of breath, an ambulance took him to the hospital. An autopsy commissioned by his family found ‘extensive bleeding caused by a severe beating.’”
Since the Ferguson Effect kicked off in 2014, many urban police departments can't hire or retain enough qualified officers.
Two of the officers dealing with St. George Floyd of Fentanyl in Minneapolis were rookies. The black one had all of four days on patrol before George Floyd overdosed. They charged him and sent him to prison while decrying "racism".
