This episode of Meisaku is inspired by "period drama." Meisaku and others are in the world of period drama. However, a lot of things look too contemporary.
I don't think they had 
police in the Edo period...
Eine Polizei gab’s
in der Edo-Zeit wohl auch nicht.
¿Ya existía la policía?
Ça non plus,
ça n’existe pas encore.
Non credo esistesse in epoca Edo...
Acho que polícia não existia na era Edo...
Да ведь не было в эпоху Эдо полиции…
