We must remain staunch in our defense of the Second Amendment. Years ago I waffled occasionally, giving them this and that in the hopes it would mollify. No more. Every time the Bidens of the world exploit tragedies like these, I get stronger in my defense of the Second. Now I’m like an ox. I might even turn into a gun nut. What we should do to minimize these tragedies is examine the causes and try to intervene before these people can act.
