In Captain America: Civil War, the Winter Soldier (Steve Rogers's childhood friend Bucky Barnes) is sought for his role in an assassination and located in Bucharest, Romania. We know it is Bucharest because they tell us he is in Bucharest, print the word "Bucharest" on the screen in big letters, and subsequently refer to "back in Romania."
The police that come to bust him are German special forces. We know this because they have German on their uniforms, they speak German, and they are referred to specifically as German special forces by our protagonists.
My question: why are Germans arresting people in Romania?
