Ex-Detective Involved In Arbery's Death Lost Power To Arrest Last Year

Gregory McMichael, a former law enforcement officer, faced issues with his certification due to incomplete training from 2005 to 2010. Despite receiving a waiver in 2014, further problems led to the suspension of his certification in 2019, after which he retired. Recently, McMichael and his son were charged with murder and aggravated assault after a video showed them pursuing and killing Ahmaud Arbery, a black man they suspected of burglary. The case has prompted investigations into potential misconduct by district attorneys and consideration of hate crime charges by the US Justice Department.
