I read that the opposite way. The World Government has been hiding its conflict with Luffy since Arabasta, and on to Enies Lobby and the battle with Moria. They are embarassed that they haven't stopped him -- especially since he's a "good guy" with the potential to turn people against the WG. If he was caught, he would be on Level 6.Originally Posted by Death BOO Z
Also, all the pirates you mentioned are on level 6. The WG basically had to acknowledge Crocodile's arrest, since they had to replace him, and didn't want the public thinking a pirate took him down.
