Set the innocent citizen free, and see
that whomever accused him falsely...
Wir befreien den unschuldigen
Bürger und sorgen dafür,
Liberar al ciudadano inocente,
y asegurarnos de que quien lo acusó…
Nous allons libérer cet innocent.
Vamos libertar o inocente e nos
certificar de que o acusador
Мы освободим невиновного.
