That means deportations. German deportations. Deportations that don’t work, in other words. Migrants deported for criminal offences just turn around and come right back to Germany again. Why, how criminal or something. That they’re able to do so, I mean.

Thousands of deported migrants reenter Germany – Nearly 6,500 people deported from Germany sneaked back to the country over the past three years, police told Bild newspaper.
Citing federal police statistics, the newspaper said 6,495 foreigners had returned or tried to return over the past three years.
During that period, the number of returnees increased by 74%.
“These numbers reveal the enormous gaps in Interior Minister Nancy Faeser‘s security policy.”
