Microphone in hand, Ohio Gov. Mike DeWine (R) had just finished remarking on the size of the crowd that was crammed tightly into the brick-covered main street of the Oregon District in Dayton, Ohio, on Sunday night when a single voice rang out.

“Do something!” the person shouted. Seconds later, another voice echoed the demand. Others quickly joined in, “Do something!” they yelled. Their cries grew louder with each iteration until what started as just a smattering of voices had morphed into a deafening chant that reverberated around the historic street near where nine people were killed and 27 injured in the weekend’s second mass shooting early Sunday morning.

The impassioned chanting, which interrupted Sunday’s vigil in Dayton, went viral on social media and represents yet another manifestation of the public’s frustration with elected officials in the wake of back-to-back massacres carried out by people armed with assault-type weapons.
