The best editorial cartoons are able to sum up an idea, situation or news story with a single, powerful image.

Jonathan Shapiro, know throughout the world as "Zapiro," is the brilliant South African cartoonist at the Mail & Guardian, who is best known for his cartoons targeting South African president Jacob Zuma.

In his latest cartoon (featured above), Zapiro targets Jonathan Jansen, the new Vice Chancellor of the University of Free State (UFS). Jansen is accused of standing up for racism for his decision to withdraw disciplinary charges and reinstate four white students (the so-called Reitz four) accused of urinating in food that they gave to five black female cleaners as part of a 2007 video, which they made to protest against racial integration at the Reitz residence.
