Yesterday morning, students and teachers arrived at Robb Elementary School in Uvalde, Texas. The school is 81% Hispanic and serves children in the 2nd through 4th grade. It felt like any other day. Yet by the afternoon, it was not. Nineteen children and 2 adults were killed at a school which was meant to be a safe place to learn and grow. The shooter, Salvador Ramos, was 18 years old and recently bought two assault rifles for his 18th birthday.
