Carrie Johnson campaigns to keep Joanna Simpson's killer husband behind bars

Carrie Johnson has joined the campaign to keep Joanna Simpson's killer husband in jail, sharing her own experience of fear. The wife of former prime minister Boris Johnson told the crowd she felt the release of Robert Brown would be "so obviously wrong."She continued to explain that her fear surrounding the planned release of black cab rapist John Worboys drove her to action. Brown bludgeoned his wife to death with a claw hammer in their family home in October 2010. He was acquitted of murder but admitted to manslaughter.Source: PA
