How is this so much different than HA? It's not like their hangouts are unknown and unlisted and members make a big deal of showing where they belong.
The large biker crews here start puppet gangs now to do all the criminal activity so "Angels of Hades MC" end up being declared a criminal org with all it's assets seized, then they just make a new puppet org "Satan's Wings MC" and repeat.
Edit: Never mind. Hell's Angels. Maybe if HA had been around since the 1600s, nothing ;)
Its odd, because they probably could make make quite a few Yen by getting the population all wound up about a "war on yakuza" and militarize their police and build private prisons and flood their justice system with cases.
Clearly, enormous amounts of money have been made by monetizing policing in the USA, so there must be some interesting cultural difference that prevents that toxic meme from infecting Japan. Whatever it is, we could use some of those antibodies here.
