There is a lingering suspicion that the Blue House stepped into an illegal investigation of civilians and orchestrated the efforts to destroy the evidence. It all started with the allegation in 2010 that the public ethics division of the Prime Minister’s Office had engaged in unauthorized surveillance of ordinary citizens. The case seemed to have been closed with the conclusion that the public ethics division committed the crime on its own.
But the suspicion that the Blue House was potentially involved in the illegal investigations continued. Jang Jin-su, a senior official with the ethics division, announced in an interview that “the Blue House had ordered a destruction of evidence,” singling out Choi Jong-seok, who was then an administrative officer with the labor and employment office at the Blue House.
