Mistaken identity: 'You called the wrong Robert Shapiro...' - BBC News
Presenter Evan Davis said it was the worst mistake since he joined Radio 4's PM programme.
But fortunately he was still very good at answering the question.

Evan Davis had been interviewing experts about the news TV cameras can film in Crown Courts in England and Wales for the first time.

The PM programme had meant to book the famous US lawyer who helped successfully defend OJ Simpson, to discuss the development with a retired Supreme Court justice.
