[181]Bienvenu was one of two survivors of an attack in which the SNR allegedly killed two of its own agents and a driver in December 2007. He and the other survivor, Major Jean-Bosco Nsabimana, known as “Maregarege,” told friends before fleeing the country that they believe the attack occurred because they “knew too much” about crimes allegedly perpetrated by the SNR, and provided videotaped interviews to the press and a human rights organization. Human Rights Watch interviews with a judicial police officer, Bujumbura, January 2007, and a former CNDD-FDD political activist, Bujumbura, January 2008; videotaped statement by “Bienvenu,” filmed by a Burundian human rights organization in December 2007 (on file with Human Rights Watch).
