Personally, I think Roger must have negotiated the terms with the world government, and the Golden Lion could have said to Karp and sengoku when he killed the Naval Headquarters alone, and it is impossible for you to catch Roger. That is to say, if Roger does not turn himself in, the world government will have no chance to execute One Piece, and it will be destroyed. Roger's condition, I guess, should be that after he disbanded the Pirate Regiment, he was not a pirate, and the Navy must not be embarrassed.
After Roger disbanded the Pirates, the world government would not be unaware of who the members of roger's Pirates were, and there were already five known, the red-haired Shanks, Bucky, Reilly, Barrett, and Kurocas. The redhead became the Four Emperors of the Sea Thieves, Bucky was still a pirate, and the Navy naturally targeted them and took Bucky to prison. Barrett is to challenge the Slayer Order, which is self-inflicted. If Reilly is honestly coated with the Chambord Islands, the yellow ape doesn't even bother to do anything with him, Reilly helps Luffy, which is the conflict, the yellow ape means that the pirates will not withdraw the bounty, but the capture of Reilly must be fully prepared. But Kurokas is different, he is the ship doctor of Roger Pirates, and he has been living in the Twin Point Lighthouse, where he lights the way for passing ships. Nor did the world government send anyone to arrest him.
Will Roger be disciplined as soon as he says it? Talking about conditions requires chips, Roger's chip is to go to the Ultimate Island, know a lot of secrets, Roger ship except for the redhead and Bucky did not arrive at the beginning, the rest of the people went. If the world government dog jumped the wall and arrested Roger's old ministry, it would be difficult for one of Paul Jay's crew members to tell the secret of the Ultimate Island. The Great Secret Treasure is a force that subverts the world, and Oda has not yet said it, but it can be seen that the World Government is very afraid and dares to carry out a slaying order for any place where it is possible to find the Great Secret Treasure.
Another point is that the strength of roger's pirate regiment is actually much stronger than the whitebeard regiment, and in his later years, Roger fought with the whitebeard two pirate regiments, which is to play. The destruction of Locks was the real skill, and the dissolution of such a powerful pirate regiment was a good thing for the world government.
However, if they were to arrest one of them, it would be difficult to ensure that they would unite again to form a pirate group, and without Roger, it would still be a huge pirate force, not weaker than the four emperors team. Since most of them are now at ease with being civilians and not doing things, they have to get by, the bounty will not be removed, and it is good to know their identity with this case and use it to prevent trouble. Only the two youngest members of the pirate group had the idea of breaking in again, and later formed their own pirate regiments, and the rest lived as civilians.
