Jeong Do-won's strategy is simple.
Deny.
Deny.
Deny everything.
One person's testimony cannot be entirely taken as evidence; without substantial evidence, he cannot be convicted. It's been so long, he thinks he left no effective evidence.
Just one person's word to convict him?
Impossible.
"Do you think this is all slander?"
"Yes."
"I've retrieved the dossiers for these three cases; there are many doubts, just speaking of the first case..." Another three minutes, the doubts in the dossiers laid out before him, all with his signatures.
These things.
Impossible to close the case anonymously.
"Back then, why did you close such obviously problematic cases?"
"I'm very sorry, I was inexperienced at the time and didn't notice." Jeong Do-won looks sincere, yet there's a hint of mockery in his eyes.
"..."
Then.
