Joseph Kony is a Ugandan war criminal and leader of the Lord's Resistance Army, a militia accused of killing, raping and kidnapping thousands of African children.
Kony's whereabouts are unknown, and Invisible Children wants him brought to justice. The documentary was posted Monday and has since been viewed by millions online, including Brandon Sammons of York.
"It was just kind of a little wake-up call," Sammons said.
Sammons has started a Facebook group to encourage people in York to participate in Invisible Children's April 20, 2012 Cover the Night campaign. That night, people worldwide plan to blanket the streets with signs and posters with Kony's name, to make sure Kony's crimes are not forgotten.
"I know it's not much, but if everybody would do their part where they're at, it would make one, kind of, one big difference," he said.
The movement has seen a surge of support but also has its detractors, criticizing the way Invisible Children spends its money and whether sharing a link or posting a video can enact any real change. Sammons says he thinks it can.
"If we all come together and use our voice, that will bring about the change," he said. "When the government sees how many people are concerned about this issue, hopefully they'll take action."
Sammons is hoping to arrange a public showing of "KONY 2012" in York.
