Soon, the nation will begin the ritual of dissecting how today’s murderer obtained his weapon, what type it was and whether any particular proposal for gun control might have stopped him. Enough. Whatever may prove to be the case here, we know our nation is awash in too many guns, that they are too easy to get, that we allow individuals to amass insane amounts of firepower and that our systems to keep them out of the wrong hands are full of holes. We know that with shocking regularity men act out their madness with guns, destroying lives and wounding communities. Even if no law imaginable could have stopped these killings, we know that thousands die every year from gun violence that could have been prevented.
