When Schools Become a Battleground, Who is to Blame?

My husband, Dana, and I were on a bus, headed home from New York City, last weekend when we crossed into Maine and saw an American flag lowered to half-staff. “What is it this time?” I asked. Only after we arrived home did we learn of the school shooting that morning in Sante Fe, Texas, in which two teachers and eight students were killed. It seems that our flag is often flying lower these days. We are a country perpetually in mourning.
