The reason why Kim Keon-hee and Han Dong-hoon's daughter were not referred to prosecution

They weren't referred to prosecution because they are innocent, you uneducated, old, pro-liberal zombie voters.
If you don't like Kim Keon-hee or Han Dong-hoon's daughter, do they have to be prosecuted and found guilty no matter what? You idiots who haven't read a single line of the law are talking about referral or non-referral without even looking into the situation.
You internet judges sitting in your tiny rooms, acting like police, prosecutors, and judges on internet forums, conducting your own trials and handing out guilty verdicts—you brainless, pro-liberal zombie old folks.
