I don't know much about Haiti's international affairs, but I'm curious if other countries will be involved at all in the investigation of this murder (because the victim was a head of state). Complicating the situation of course, is the english and spanish speaking assailants, indicating that they might be foreigners. Will the D.E.A. (audio of the event being shared has a clip of someone yelling "this is a DEA operation, stand down" in a southern american accent) be expected to make some sort of statement regarding this? Should we believe them without a formal investigation and evidence?
