Students across the country say they are deeply affected by gun violence, yet they are too young to vote for policies and politicians that could make changes.

That issue spurred Concord middle school students to create a six-minute documentary for C-SPAN's national StudentCam contest, which won third place.

The video, called " Not Me: Children Caught in the Crossfire,” was produced by eighth graders Felica Curtis, Ellie Epstein and Coco Shen. It explores school shootings and the need for gun reform.

"There are many regulations that could be passed to prevent these shootings that aren't being passed, such as background checks," Epstein said on Greater Boston. She said background checks could be strengthened and also noted other measures including safe storage and an assault weapons ban.

Curtis said gun violence isn't talked about enough. "It's kind of become normal in our country, but this is our reality as students," she said. "We go to school every day and in the back of our minds thinking, 'We could die in a place where we're supposed to grow and learn.'"

The students had optimism that things will change.

"We will definitely advocate for more safety for children in schools," Shen said.
