The two-street-long block where the Federal Intelligence Agency was headquartered in Berlin was completely blockaded. The outermost defense was ordinary anti-riot police who wore bulletproof helmets and vests, and carried bulletproof shields. They were completely armed, but no one knew against who. Germans were different from Hua Xia people in that they didn't like to join in the excitement. As a result, nearly all the Germans avoided the area after the streets were blockaded. Residents in the area also didn't dare peek their heads out, and they locked their doors and windows tightly.
