Sippenhaft is an old Nazi policy under which family members of criminals were held equally responsible and punished. Now a Swiss political party is using a racist and xenophobic poster to revive the practice.

The poster shows three white sheep booting out a black sheep, with a caption that translates to "for more security." It's part of an effort to drum up support for a deportation policy in which entire immigrant families would be kicked out of Switzerland if their children committed a violent crime, a drug offense, or benefits fraud.

It's not some fringe, extremist, right-wing political party that's trying to collect 100,000 signatures for a referendum on the policy. Rather, it's the country's largest party—the Swiss People's Party. Back in 2004, this party used the image of black hands reaching into a pot of Swiss passports to successfully campaign for stricter immigration laws. More recently, it proposed banning the construction of minarets.
