The mass sexual assaults outside the central train station in Cologne, Germany, on New Year's Eve are currently the subject of ongoing police investigations in the country and heated debate throughout Europe.

Many women reported being robbed or sexually assaulted by a group of men that night. Cologne police are being heavily criticized for their failure to prevent the assaults.

Making matters worse, the city's mayor has been widely excoriated for suggesting earlier this week that women could protect themselves on the street by keeping an arm’s length distance from men.
