Video: Tamir Rice shooting: two Cleveland police officers placed on leave "The investigation - all the video evidence, all the scientific evidence - will show everyone exactly what happened," he said. Williams urged parents to educate youngsters on the dangers of all weapons, including convincing replicas like the so-called "Airsoft" pellet gun Rice had been carrying. "Our kids need to know that guns aren't toys," he said. Visiting the scene of the shooting, the boy's father, Gregory Henderson, questioned why police didn't use a Taser electric stun gun in lieu of lethal force. Tamir Rice's death came as Americans awaited a grand jury's decision on whether to indict a white police officer in the St Louis, Missouri suburb of Ferguson for the fatal shooting in August of black teenager Michael Brown. That shooting, in a majority black community with an overwhelmingly white police force and city council, prompted a national debate about race and law enforcement.
