The video made public on Wednesday shows Tamir Rice being shot within 1½ to 2 seconds of a patrol car stopping near him at a park in Cleveland on Saturday. It shows the boy reaching in his waistband for what police discovered was a pellet gun that shoots non-lethal plastic projectiles. He died the next day.

Tamir’s family said in a statement released by their attorneys that they hope Cleveland police and Cuyahoga County prosecutors “thoroughly examine” what happened at the park that day.

“It is our belief that this situation could have been avoided and that Tamir should still be here with us,” said the family. “The video shows one thing distinctly: the police officers reacted quickly.”
