Vice President Kamala Harris toured on Saturday the bloodstained classroom building where the 2018 Parkland high school massacre happened, then announced a program to assist states that have laws allowing police to temporarily seize guns from people judges have found to be dangerous. Harris saw bullet-pocked walls and floors still covered in dried blood and broken glass left behind from the Feb. 14, 2018, attack at Marjory Stoneman Douglas High School that killed 14 students and three staff members and wounded 17.
