An act redefining Statute of Limitations in kdramas.
Section 1. Whereas in real-life law, the Statute of Limitations “sets the maximum time after an event that legal proceedings based on that event may be initiated”.
Section 2. Whereas to give Kdrama Police a fighting chance in solving old crimes, one or more of the following must occur near the end of the Statute of Limitations:
(a) A new evidence such as dead body, old records, DNA sample, Corruption_Bribes_Record_1998.xlsx, etc. must surface.
(b) A new witness must recognize something or someone on the news and connect the dots.
(c) An old witness who was bribed to lie must feel guilty and decide to tell the truth.
(d) The original perpetrator must feel antsy and go on a silencing-witnesses spree instead of laying low like all wise masterminds.
(e) The son/daughter of one of the wronged parties must have grown up by this time and must work with the police, directly or indirectly, to solve the crime before the statute passes.
Section 3. Should events in Section 2 be insufficient to solve the crime, the Statute of Limitations, must, on further examination, be moved due to some clerical error in recording the original date of the crime, thus giving the police an extra tense day by which to cram filing of the evidence.
Section 4. Should a criminal mastermind fail to be prosecuted properly using Sections 2 and 3 of this Act, he or she must meet the following ends:
(a) Die after vowing to never ever ever surrender or feel bad about his/her crime.
(b) Go crazy. For whatever reason.
(c) Be forgiven by the aggrieved party after confessing that it was an accident and he/she was just too scared to confess at the time. Applicable IF AND ONLY IF the defendant is the mother/father of half of the OTP, giving the aggrieved party no choice but to forgive his/her lover’s parent.

Aww! You got that? It’s what I had in mind for most of the post, but didn’t want to use pics from PP because some people might not be familiar with it…
