St. Valentine's Day Massacre

S1 E4: In 1929, seven members of Bugs Moran's gang are assassinated in a garage by Al Capone's henchmen. This event was taken up by the press who named it the "Saint Valentine's day Massacre". Carried out during the prohibition, those killings became the newsworthy symbol of gang wars - they consolidated the image of the Italian mobster in the American collective imaginary.
