[JURIST] The chief federal prosecutor in a terrorism case marred by prosecutorial misconduct resigned on Monday. Richard Convertino won convictions [DOJ statement] against four terrorism suspects in Detroit in 2003, but the government later had them tossed out [JURIST report] because possibly-valuable defense information was not turned over by the prosecutors as required. Convertino later sued then-Attorney General John Ashcroft [JURIST report, PDF complaint], claiming that the Justice Department had "exaggerated its performance in the war on terrorism, interfered with a major terror prosecution and compromised a confidential informant". Convertino will likely avoid sanctions by leaving the DOJ; his first private case will be defending a police officer charged with murder in a controversial shooting [WXYZ report]. AP has more.
