Samura could also reach out to the Corsairs, and encourage them to start raiding into Kusari as well.
Everything that makes the current government seem unable to prevent crime plays into Samura's hands. It lets them say "things were never this bad when the Emperor was in charge!"
I would also urge the Kusari Government to allow Bounty Hunters to also operate in New Tokyo, to help draw out the Dragons and AFA and provide backup whilst KNF numbers are low.
