When presidential hopeful Victoire Ingabire, a Hutu, returned to Rwanda after a long absence she immediately visited a memorial to Tutsis killed in the 1994 genocide and asked why Hutus who also died weren't remembered. She then told Hutu prisoners she would get them out of chains.

For these actions, the 41-year-old Ingabire was arrested, charged with genocide ideology and could be sentenced to more than two decades in prison if convicted.

It's been 16 years since 800,000 Rwandans, the vast majority of them Tutsis, were slaughtered by Hutus. With the nation still grappling with ethnic divisions almost a generation later, Ingabire's case has become a test of where Rwanda stands in its effort to move past the genocide — and how much freedom the government of President Paul Kagame, a Tutsi, will allow its people.
