The first interior images of the Uvalde school shooting were released. Last month, the mass shooting at Robb Elementary School in Uvalde, Texas, left 19 students and two teachers dead. The new pictures show police officers in the hallway 19 minutes into the massacre armed with even more firepower than previously thought. Also, the Department of Public Safety director, Steve McCraw, told the public hearing that the classroom door the cops waited to open was unlocked.
