Print All week, we will be publishing essays from San Diegans about last week’s rioting by a mob incited by President Donald Trump in Washington, D.C.

During the terrible events of Sept. 11, 2001, and grieving for all the lives lost, I remember being thankful the people’s house, the Capitol building, that beautiful dome, was not destroyed and still stood proudly. I never could have imagined that almost two decades later, its security would be breached not by foreign terrorists but by domestic terrorists intent on disrupting the work of our nation.
