Another ingredient has been added to the ongoing debate over revising the Juvenile Law, with crime victims' families clamoring for their right to information and for an end to unfair investigations.

In a Monday gathering at the office complex of Upper House members, Kimio Okazaki, whose 14-year-old son was killed in an assault by his schoolmate in 1998, criticized investigative authorities for neglecting to hear the family's opinions during the course of the investigation.

Based on police investigations, the family court concluded last August that Satoshi Okazaki died in October 1998 after being hit by another boy of the same age in a one-on-one fight that the victim provoked.
