Joe Ga's main target is not the mob boss, Boris. It's fine to kill him incidentally, but when he is useful, it's a different situation.
With this guy around, it's a breeze for Monica to take down those corrupt cops.
With a witness, it's highly likely that these rogue cops will end up in prison.
But without a witness, those high-ranking rogue cops might just get away with an internal investigation.
They're bound to lose their badges, but the threat of prison isn't significant.
As long as they hold onto this guy, Monica can easily manipulate those cops.
Once everyone has negotiated and handed this guy over to the police system, Joe Ga believes he definitely won't live to see the trial.
Joe Ga has no interest in wasting energy on the mob, so he arranges for the Jazz Squad, with the girl Estelle, to make a trip to the mob's warehouse, lock up Boris, and then starts having Danny Logan spread the news.
"The Belarusian Mob raided, lots of evidence about rogue cops inside."
