Police, government officials and journalists say they failed the women attacked in Cologne, Germany on New Year’s Eve. Groups of young men sexually attacked and robbed women that evening. The attacks occurred outside Cologne’s main train station. Prosecutors said police received 945 complaints from the victims of the attacks. More than 430 were for sex crimes. Prosecutors named 35 suspects, 32 of them from North Africa. The attacks reduced support for immigration in Germany. A study by YouGov, a European polling agency, found 62 percent of Germans believe there are too many asylum seekers in Germany. That is up nine percentage points from before the Cologne attacks. The Cologne attacks led to painful debates about government, news media and police. Some questioned whether Germany should accept more immigrants.
