Four years ago, Simon Neumeyer enrolled in the Saxony State Police Academy in the eastern German city of Leipzig as a 19-year-old cadet.
"At the time, I naively thought the police were 100% committed to law and order," he remembers.
His naiveté began to wear off on the academy's target-shooting grounds while he and his fellow cadets, guns in hand, listened to a lecture from their commander.
"He told us we have to shoot well, because there are many refugees coming to Germany," Neumeyer recalls. "I thought to myself: 'Wow. This is very racist.'
"Later, my ethics teacher complained about foreigners celebrating loudly in the city center on New Year's Eve and that this was his home. These teachers were basically passing their racism on to us cadets."
Neumeyer tells NPR he finally spoke up one day when an academy teacher used the N-word in class. To his surprise, he remembers his classmates not defending him, but loudly defending their teacher.
