This is the only report I've seen from the Arab League Observer Mission that has been so roundly criticized by Western political figures. The report seems to focus on the details and forgoes any summary statements about the violence in Syria. There also seems to be a lot of evidence that the Mission was not very well organized to handle a lot of very tense situations that one would expect.
One finding that was of special interest to me is their observations about an unknown "armed entity" or "entities" that were associated with violence against the government and citizens. This could be the mercenary forces that independent sources report as being supported and inserted into Syria from nearby countries to spread violence and chaos. See this, this, this, and this for more details.
