Trying to make sense of this message from Columbia. How did they learn about the protest? Did the organizers request permission? Did the administration deny it? All the important questions are hidden behind Columbia's emphasis on simply following rules.

Whoever these people in the boat were, this was an act of premeditated murder. We do not even know where exactly this happened and whether the supposed drugs were destined for the US. One cannot just kill people in international waters. A further erosion of the rule of law and US moral leadership.
