Lee Dong-jin's explanation is absurd

If the movie had included even 5 seconds of a scene where Park Chung-hee mourns and suffers over Yuk Young-soo's death, the audience would have thought it was an act committed solely by the KCIA..
He says things like, "Only his own podium was replaced with bulletproof material," and "His wife was shot, yet he persevered with his speech"—how can the audience separate Park Chung-hee from the KCIA under those circumstances?
He claims it's fiction, yet he conveniently leaves out those exact parts... It's absurd when they say, "You're seeing it wrong" or "You're misinterpreting it" lol
I wonder what his reason is for asserting that the audience cannot conclude that Park Chung-hee was the mastermind.
