Kirin tendered his resignation on December 29th, a week after taking part in a wild-boar hunting trip with former special police commander General Mladen Markac, who surrendered to the International Criminal Tribunal for the former Yugoslavia (ICTY) in 2004 and was freed later that year to await trial at home.
Kirin je podneo ostavku 29. decembra, nedelju dana pošto je sa bivšim komandantom specijalnih jedinica policije, generalom Mladenom Markačem bio u lovu na divlje svinje. Markač, koji se Međunarodnom krivičnom sudu za bivšu Jugoslaviju (MKSJ) predao 2004. godine, pušten je iste godine da suđenje čeka kod kuće.
