In 1955, the Soviets gave East Germany authority over civilian movement in Berlin, passing control to a regime not recognized in the West.  Initially, East Germany granted "visits" to allow its residents access to West Germany. However, following the defection of large numbers of East Germans under this regime, the new East German state legally restricted virtually all travel to the West in 1956.  Soviet East German ambassador Mikhail Pervukhin observed that "the presence in Berlin of an open and essentially uncontrolled border between the socialist and capitalist worlds unwittingly prompts the population to make a comparison between both parts of the city, which unfortunately does not always turn out in favour of Democratic [East] Berlin." 
The unwillingness of German judges to lock up unsocialized walking time-bombs already known to the police has claimed a victim in Cologne on New Year’s Eve. Two criminal foreigners, free to terrorize their neighbors despite drug-related and violent crimes, killed a Turkish husband and father who tried to get them to behave. It happened in a sector of the city called Bickendorf — a district notorious for years for immigrant violence and bordering on the thoroughly Islamized Ehrenfeld. There was also knife-play at night in the immigrant milieu of right-bank Cologne-Vingst, where “Antifa” pastor Meurer is collecting for the building of a mosque and reading masses against Pro-Köln. But no one was killed.
