50 years on, families of the Guildford Four are still seeking justice

The case of the Guildford Four is considered one of the worst miscarriages of justice in British legal history. Fifty years ago this month, four young people were falsely accused of carrying out two pub bombings in Guildford, England, and sentenced to life in prison. It took 15 years for them to be released and their sentences quashed. Decades later, their families say the fight for accountability and justice is still not over.
