The numbers involved in France’s largest child abuse trial are staggering: 299 alleged victims, sexually abused in nine hospitals over 25 years - all by one doctor, prosecutors say.

Defendant Joël Le Scouarnec's chillingly detailed notebooks —which he used to document sexual violence that spanned decades — are central to the trial.

The trial for former surgeon Joël Le Scouarnec, who is charged with raping or sexually assaulting 299 victims over three decades, is set to be the largest trial of its kind in French history. NBC News’ Molly Hunter reports on how the country and activists groups are reacting to the allegations against the 74-year-old.
