If a man is suspected of murder, arson and speeding, any prosecutor who focuses only on the last charge risks ridicule.

Many economics students are unhappy with what they are being taught. A network of 62 groups from around the world has drawn up a petition calling for more “pluralism” in instruction.

They also want less abstract theory and more study of actual economies. The reproaches are just, but the students’ reform agenda is insufficiently radical.
