The former police detective whose actions in the fatal shooting of Ahmaud Arbery in Georgia were defended as a citizen’s arrest was stripped of his law enforcement certification and power to arrest a year before the deadly encounter.
Gregory McMichael’s certification was suspended in February 2019 after repeated failures to complete required training, according to documents from the Brunswick Judicial Circuit District Attorney’s Office, including a warning in 2014 that McMichael had neglected to finish mandatory firearms and use-of-force courses.
Gregory McMichael told police they believed Arbery was involved in local burglaries. A video shows a man who is believed to be Arbery entering a house under construction moments before the shooting, though the property owner says nothing was taken.
