No the true common sense is that he just knocked a little girl, which whose' actions don't pose that great a threat to the world government. With Fujitora and all the marines there, and civillians that were saved (including Kyros), I'm sure they'd be able to peace together roughly what happened.

And even if they don't know what really happened and raise his bounty just for his involvement alone, it still wouldn't increase that much. In fact if they don't know what really happened it's more likely the bounty increase will be less, cause they can't just assume that he did something really big that would see him as a threat to the World Government.
