When tragedy strikes, our immediate reaction is one of shock and horror. In its aftermath, frustration and anger, and the desire to make sure nothing like it happens again.

It should come as no surprise then that in the wake of the El Paso, Texas, and Dayton, Ohio, shootings, which left 31 dead and dozens more injured, a hurt nation is demanding restitution and action. Tragedy inspires change. But inspiration won’t be enough to make change useful or lasting.
