A once-in-a-century pandemic cannot be the only thing that slows mass shootings in America.

Michelle and I grieve with the families of the victims of the shooting in Boulder, just as we grieve with the families of the people killed in Atlanta and everyone else who has lost a loved one to gun violence.

We are also grateful for the courage of Officer Eric Talley, who ran into danger to protect others, and we hope his memory and the memory of all those we’ve lost will not be in vain. Because in addition to grief, we are also feeling a deep, familiar outrage that we as a nation continue to tolerate these kinds of random, senseless acts day in and day out without taking any significant action — an outrage that people in Colorado have known far too often over the years.

In so many ways, our lives may soon start to return to normal after a long, difficult year filled with so much loss. But in a normal life, we should be able to buy groceries without fear. We should be able to go to school, or go out with our friends, or worship together without mentally planning our escape if someone shows up with a gun. We should be able to live our lives without wondering if the next trip outside our home could be our last.

We should. But in America, we can’t.

It is long past time for those with the power to fight this epidemic of gun violence to do so. It will take time to root out the disaffection, racism and misogyny that fuels so many of these senseless acts of violence. But we can make it harder for those with hate in their hearts to buy weapons of war. We can overcome opposition by cowardly politicians and the pressure of a gun lobby that opposes any limit on the ability of anyone to assemble an arsenal. We can, and we must.
