What did the last words of detective Conan 632 gin mean?

Finally, King said, "Hum, do you want to be arbitrary? That bastard hasn't changed a bit. It's really annoying I really hope that, as you said, a detective like Sherlock Holmes can only see it in novels ... "

Personally, Gin here should have noticed that this "Akai Shuuichi" was forged by Bourbon, because he didn't believe in Hideyoshi's death. In order to test the reaction of the FBI and whether he really died, he gave up attacking him. He has believed that Akai Shuuichi is really dead.

There is another version that I saw in the post bar:

Finally, there, Kim could have killed Akai Shuuichi, but after hearing the news of Belmore and giving up the sniper program, he said something: Hum, is he arbitrary? That bastard really hasn't changed a bit. Really annoying (water pity is helpless: alas, who are you talking about). I really hope that, as you said, you can only see detectives like Sherlock Holmes in novels. ...

Then I read the above words several times and probably saw some clues.

Since the boss ordered not to kill for a while, there must be a reason. Kim said the last sentence, and Belmore said that the boss was very cautious. It seems that the boss has noticed the existence of another more dangerous silver bullet (Shinichi). Although I don't know who he is, killing Xiu will definitely cause an uproar, which will lead to silver bullets grasping clues and threatening the organization.

So the person Gin was talking about, I think, was either Belmore or Bourbon.
