Apology campaign for British Nazi code-breaker

There’s a campaign under way in Britain to press the government to issue an apology in the case of Alan Turing. Turing is considered the father of the modern computer and contributed to the defeat of Germany during World War Two by cracking secret Nazi codes. Turing committed suicide in 1954 after being prosecuted for being homosexual. Anchor Lisa Mullins finds out more about the campaign from Richard Gill, a professor of mathematical statistics at the University of Leiden in the Netherlands.
