I call BS too. Who cares what Monday Morning Quarterbacks think when viewing a video frame by frame? That's not how strikes happen. In the fog of war, decisions are made in seconds. And the commander who ordered the strike was being advised by his JAG lawyer in real time. You have ZERO actual evidence that the commander targeted the drug dealers rather than the boat.
This is an absolute nothing burger. But it does keep you people outraged. 
If the video reveals that those two people were clinging to bits of wreckage having no resemblance to a boat, this would be good evidence of what or who was targeted. This is why it is highly unlikely that an unaltered video will ever be released for public viewing.
It may be a 'nothing burger' to you. It was something to the two deceased.
'Fog of war' and 'nothing burger.' You do like to collect and repeat these catch phrases used in the media.
