Luffy did a CDs face in and the WG send Kizaru and never ever again pressed the issue unless they happened to come across him.
do not get me wrong here. it feels like the navy is not really chasing him because of that.
especially since Fujitora, a guy under direct order of the CDs, let him off the hook.
most likely the CDs would rage, but nothing will come from it.
the WG can not afford to spread themselves thin and leave their own territory exposed by invading a yonkos territory.
though I would really like if an admiral got the akainu treatment by a healthy yonko.
