The Heraldic Eagle, or Reichsadler is still to this day used as the coat of arms of the German empire. Its use in the coat of arms, and on German symbolism generally picture an eagle with curved wings and a red open beak.
Nazis used a heraldic eagle with wider and straighter wings, and no apparent colors.
In October 2018, a Philly cop was noticed wearing the said eagle on his forearm, and was frowned upon by the national press. However, no apparent sign appeared to me to link this type of symbolism directly to nazism (especially since it wasn't known if the eagle was carrying any swastika).
Is there any way to dissociate the Reichsadler from nazism?
How does an heraldic eagle become a nazi symbol?
