Columbine. Sandy Hook. Parkland. Uvalde. What do we do now?

Columbine. Parkland. Pulse. Virginia Tech. Sandy Hook. Las Vegas.

Now Buffalo and Uvalde. Two more tragic mass shootings, added to the heartbreaking list of the worst such incidents in American history.

Does nothing change? That is what it can seem like. Politicians make familiar utterances about thoughts and prayers, and there’s a spurt of citizen energy and media attention, but that fades, and big things intended to lower the nation’s shocking level of deaths caused by firearms don’t happen.

It may be true that Washington has taken little concerted action on gun violence in recent years. It’s a difficult, complex issue – and national politics is polarized and too often gridlocked.
