My memory of the action was that they also revealed that extended family members were known and could be utilized for further demonstrations.
And, I suspect, most all of us.
I am not sure that the new German leadership, even if most of them are holdovers from the previous Statsi leader, remembers how the Soviets did thing.
One hopes that the next demonstration doesn't get dropped off at the doorstep of the Bild, the Neues Deutschland or Junge Welt to get their attention.
