For the first time in South African history, a court on Wednesday sentenced a white woman to prison for making racist comments, a judgment that has given some hope that charges of racism will be treated more seriously.

Vicki Momberg was sentenced to up to three years in prison for an incident that took place in Johannesburg in February 2016, when she was filmed making derogatory comments toward the black police officers who had responded to her call of a reported robbery. She was convicted last November of four counts of "crimen injuria,” or the use of racially offensive language.

In the viral video, Momberg can be heard talking to someone on the phone about the police officers dispatched to the scene. She referred to them as "kaffirs,” an offensive and derogatory term for black South Africans that was used during apartheid, and which lawmakers have in recent years tried to criminalize along with other forms of hate speech.

"The kaffirs here in Joburg are terrible,” Momberg said. "I’m so sick of it. I really am.”

At one point, an officer approached her. While attempting to speak with Momberg, she yelled, "I don’t care. I do not like a single black in Joburg.”

Momberg then made comments about the difference between black South Africans in Johannesburg and Durban, claiming that the former group is "opinionated, they’re arrogant, and they’re just plain-and-simple useless.”

She went on to tell the officer, "I am happy for a white person to assist me, or a colored person, or an Indian person. I do not want a black person to assist me.”

The exchange continued for several minutes — and the clip broadcast on South African news station Eyewitness News appears to have been edited for time — and reached a peak when Momberg threatened to run black people over with her car and shoot them.

"If I see a kaffir, I will drive him over,” she said. "I have a gun — I will shoot everybody.”

Momberg’s attorney attempted to use her psychological state — having just been robbed — to explain her behavior, and Momberg said in her testimony last November that she had been "intimidated” by the officers because the person who allegedly robbed her was black. But Pravina Raghoonandan, the magistrate who presided over the case, disagreed with them both in her ruling, stating that Momberg had shown no remorse for her actions.

South Africans on Twitter largely supported the sentencing, with many celebrating it as a step in the right direction to combat the deep-rooted racism in the country.
