Question: Who was the leader of the Lord's Resistance Army (LRA) that abducted Grace Akallo in Uganda?

full_context: Document 1: Lord's Resistance Army insurgency (2002–05): The period from 2000 to 2006 of the Lord's Resistance Army insurgency in northern Uganda begins with the assault of the Uganda People's Defence Force (UPDF) upon LRA strongholds in South Sudan. This in turn led to a series of retaliatory attacks by the Lord's Resistance Army of an intensity not seen to since the mid-1990s. International awareness of the conflict gradually grew and in September 2005, the International Criminal Court issues warrants for the arrest of senior LRA commanders, including Joseph Kony.
Document 2: Lord's Resistance Army: The Lord's Resistance Army (LRA), also known as the Lord's Resistance Movement, is a rebel group and heterodox Christian cult which operates in northern Uganda, South Sudan, the Central African Republic, and the Democratic Republic of the Congo. Originally known as the United Holy Salvation Army and Uganda Christian Army/Movement, its stated goals include establishment of multi-party democracy, ruling Uganda according to the Ten Commandments, and Acholi nationalism, though in practice "the LRA is not motivated by any identifiable political agenda, and its military strategy and tactics reflect this". It appears to largely function as a personality cult of its leader Joseph Kony, a self-declared prophet whose leadership has earned him the nickname "Africa's David Koresh".
Document 3: Sahar Gul: Sahar Gul (born c.1998) is an Afghan teenager who was subjected to torture and abuse by her husband's family in the town of Puli Khumri when she was illegally married as a child bride.

Three of her in-laws were found guilty of attempted murder and sentenced to 10 years in prison, but later freed after an appeals court voided their convictions. American Attorney Kimberley Motley represented Gul in Supreme Court upon hearing of the in-laws release. Gul became the first victim of a crime that was represented by an Attorney for a criminal proceeding. In a landmark decision the Supreme Court, and after the case was decided twice by the Appellate Court, Gul's in-laws, brother and husband who were never originally tried were convicted and sentenced to five years in prison.

Document 5: Red Hand Day: Red Hand Day or International Day against the Use of Child Soldiers, :February 12 each year, is an annual commemoration day on which pleas are made to political leaders and events are staged around the world to draw attention to the fates of child soldiers, children who are forced to serve as soldiers in wars and armed conflicts. The aim of Red Hand Day is to call for action against this practice, and support for children who are affected by it. Children have been used repeatedly as soldiers in recent years including armed conflicts in the Democratic Republic of the Congo, Rwanda, Uganda, Sudan, Côte d'Ivoire, Myanmar, Philippines, Colombia, Palestine, and Ukraine. Estimates on the number of children engaging in armed conflict around the world showed no change between 2006 and 2009. Rehabilitation for child-soldiers returned to their communities ranges from inadequate to non-existent.

Document 12: Human trafficking in Uganda: Uganda is a source and destination country for men, women, and children trafficked for the purposes of forced labor and sexual exploitation. Ugandan children are trafficked within the country, as well as to Canada, Egypt, the United Arab Emirates, and Saudi Arabia for forced labor and commercial sexual exploitation. Karamojong women and children are sold in cattle markets or by intermediaries and forced into situations of domestic servitude, sexual exploitation, herding, and begging. Security companies in Kampala recruit Ugandans to serve as security guards in Iraq where, at times, their travel documents and pay have reportedly been withheld as a means to prevent their departure; these cases may constitute trafficking. Pakistani, Indian, and Chinese workers are reportedly trafficked to Uganda, and Indian networks traffic Indian children to the country for sexual exploitation. Children from the Democratic Republic of the Congo (D.R.C.), Rwanda, and Burundi are trafficked to Uganda for agricultural labor and commercial sexual exploitation. Until August 2006, the terrorist rebel organization, Lord’s Resistance Army (LRA), abducted children and adults in northern Uganda to serve as soldiers, sex slaves, and porters; while no further abductions of Ugandan children have been reported, at least 300 additional people, mostly children, were abducted during the reporting period in the Central African Republic and the D.R.C. The Government of Uganda does not fully comply with the minimum standards for the elimination of trafficking; however, it is making significant efforts to do so.

The organization promotes its cause by dispensing films on the internet and presenting in high schools and colleges around the United States.
Document 14: Lord's Resistance Army insurgency (1987–94): The period from 1986 to 1994 of the Lord's Resistance Army insurgency is the early history of the ongoing insurgency of the Lord's Resistance Army (LRA) rebel group in Uganda, which has been described as one of the most under-reported humanitarian crises in the world. The Lord's Resistance Army was formed in early 1987 out of the conflict following the successful rebellion of the National Resistance Army (NRA), though remained a relative small group through the counterinsurgency of the NRA. As the peace talks initiated by Minister Betty Bigombe failed Sudanese support to the LRA intensified the conflict.
Document 15: Rape during the Kashmir conflict: Since the onset of the insurgency in Jammu and Kashmir in 1988, rape has been used as a weapon of war by Indian security forces; comprising the Indian Army, Central Reserve Police Force (CRPF) and Border Security personnel, against the Kashmiri population. The frequent rape of Kashmiri Muslim women by Indian state security forces routinely goes unpunished. Many women have become victims of rape and sexual assault in the conflict. According to scholar Seema Kazi, separatist militants have also committed rape to some extent, although not comparable in scale with that by the Indian state forces.
