Police officers react to Uvalde massacre in disturbing new video.

Newly released body-camera footage from the Uvalde massacre shows police officers vomiting and sobbing after discovering the bloodied bodies of young students in one of the classrooms. The footage was broadcast on CNN ahead of the one-year anniversary of the shooting. The parents of the victims approved the footage's release, hoping it would spur action to prevent future shootings. District Attorney Christina Mitchell Busbee has blocked the footage from being released to the public until she’s done with her inquiry, prompting CNN to share it with the parents.
