A screening in northern Uganda of the viral video about militia leader Joseph Kony, produced by the U.S. charity Invisible Children, drew a puzzled and hostile reaction from an audience that included many victims of Kony’s Lord’s Resistance Army, Al Jazeera and Canadian daily the National Post report.

The half-hour video, released online last week by the advocacy group, has been viewed more than 75 million times; triggered debates over the value of social-media activism and global efforts to capture Mr. Kony, who is wanted by international bodies on war-crimes charges; and focused scrutiny on Invisible Children’s finances and governance.

The showing in the village of Lira, arranged by a local charity, ended with viewers pelting the screen with rocks and deriding “Kony 2012″ as a promotional tool for the American nonprofit.

“We wanted to see how our local people were killed,” one viewer said afterward. “These are all white men [in the video], different than northern Uganda.”
