According to the Bushido Shoshinshu (the "Code of the Warrior"), a samurai was supposed to commit seppuku (also harakiri, "belly cutting", a form of ritual suicide) upon the loss of his master. One who chose not to honor the code was "on his own" and was meant to suffer great shame.

Because the former samurai could not legally take up a new trade, or because of pride were loath to do so, many rōnin looked for other ways to make a living with their swords. Those rōnin who desired steady, legal employment became mercenaries that guarded trade caravans, or bodyguards for wealthy merchants. Many other rōnin became criminals, operating as bandits and highwaymen, or joining organized crime in towns and cities. Rōnin were known to operate or serve as hired muscle for gangs that ran gambling rings, brothels, protection rackets, and similar activities.

I’ve said it before, and I’ll say it again: this was a sex trafficking operation. The PR against cops and the 2A was just added flavor for the deep state’s desires.
