I don't think anything has to be changed, any Hogosha commiting crimes (Based on the Kusari legal Codex) should be treated as a Criminal.
I don't think that the Hogosha faction should be treated as a coorporation or a police/military force.
I'd consider Hogoshas as independents from eachother, or groups, but the action of 1 hogosha shouldn't and mustn't reprensent the actions of the entire NPC faction.
If Kishiro and GMG want to be 1 faction, allies or husband and wife, shouldn't affect the way Hogosha players are treated.
