SEOUL, Oct. 19 (Yonhap) -- The inaugural chief of South Korea's newly launched Serious Crime Investigation Agency (SCIA) reaffirmed his commitment on Monday to ending the "politicization" of investigations, following a major overhaul of the criminal justice system. Kim Ji-yong, appointed to lead the SCIA on Thursday, told reporters, "The previous prosecution caused various harms, such as abusing investigative powers, and I think the root cause of that lies with the politicization of investigations."
