The NBA cancelled its playoff games after the Milwaukee Bucks refused to take the court for their game Wednesday. The boycott is the Bucks' response to the shooting of Jacob Blake, a Black man shot in the back by police officers Sunday in Kenosha, Wisconsin. Video shows Blake, trying to get into his automobile, with an officer pulling Blake's white T-shirt, then firing several shots at close range into his back. Blake's father says he was told his son is paralyzed from the waist down.Athletes in other sports praised the boycott.
