Despite the rhetoric, I have the distinct impression that whoever was in charge of the area at the time most likely did a good job - the area was kept secure and within a very short space of time, considering the environment, a refrigerated train was located and moved into place. Bodies were collected, bagged and placed in the container. The black box was located and kept secure.
The men involved were not from a highly trained established army but a rebel group with political motivation. They seem to have done pretty well in the circumstances.
