Politicians often siphon public funds to further their political careers and also pay gangs to aid them in rigging elections. The elections since the end of military rule occurring in 1999, 2003, and 2007 were bloody affairs and were openly rigged. In 2007, ballot boxes were visibly stuffed by paid gangs and in some cases, electoral results were simply made up. Human Rights Watch estimates that at least 300 were killed due to the 2007 elections and that is considered to be a conservative estimate as cited from a Human Rights Watch telephone interview with Derrick Marco, Nigeria country director in March 2007. These measures of violence and intimidation discouraged the general public from voting. Those who did come out were subject to attacks by gangs.
