As the recent manga release of One Piece, we all know that Jesus Burgess infiltrated the Revolutionary Army HQ (Baltigo) and reported it to his Captain BB.
My question is how did the World Government know that the Blackbeard Pirates were planning on attacking the Revolutionary Army HQ. we could take note that the one who attack in Baltigo are Cipher Pol, not the Marines.
As I remember, Cipher Pol is directly serving World Government (Nobles). Even if that Information came from marines first. How did they know? Is Aokiji a spy?
