content: there was a time  Before WW2, maybe.  Nowadays Japanese cops pretty much never have to face anything willing to fight. Unless it's a Yakuza doing Yakuza business ... in which case they politely apologize for bothering him and walk away pretending to have seen nothing. They are incapable of handling something like niggers/sandniggers, willing to kill cops and passerby just because someone might have looked at them the wrong way.
