Relatives of some of the 96 Liverpool fans killed at Hillsborough had to sit through videotapes of the crush at the Sheffield Wednesday ground in 1989. The families were attending the opening of the trial of former chief superintendent David Duckenfield and former superintendent Bernard Murray. The pair deny the manslaughter of two representative victims, John Anderson and James Aspinall. Alun Jones QC for the prosecution said: 'It was not the case of the two officers being made scapegoats. We don't say that the defendants' inertia and abject failure to take action was the only problem. We say that the primary cause was the defendants' failure to close the tunnel when the order was given to open the gate. We say that amounts to manslaughter.'
