You journalists should really make a choice between giving us the facts or your own opinions. (If you choose the second, try at least show images that match with your opinions)
1. You mention that all men are being killed by Nkunda's troops but the pictures show dozens of civilians around soldiers (and they don't look like Tutsis). Would you expect that poor woman to tell you that her late husband was indeed FDLR or Maimai? There must be a reason why those twenty men were targeted among hundreds. Is it really inconceivable that some militias would fail to escape and hide in houses? Maimai are not soldiers that live in barracks. They live in villages where they have wives and kids.
2. You tell us that Nkunda's officers speak English, but your video shows Maj Muhire speaking excellent French, Bosco Ntaganda who you present as a known CNDP commander + one driving soldier who probably just wanted to impress the viewers and his friends with a few worlds of English. Oh, and by the way, the vast majority of Rwandan army officers speak French. Cross the border and check if its not too much asking...
