Espionage against a Kurdish family in germany
Because we the family must contact the German police to investigate espionage that may be leveled at the family
This mirror placed espionage against another neighbor. 
I do not understand why it's important for people to spy other people? 
One question that came up to me, I myself saw this house had not mirror on the window after the family moved there they placed a mirror on the window to control others who visit them and who usually come with them new family that has moved to new area .
