It was a cowboy from the National Guard who killed 4 Canadian solders.
What I am surprised but happy to see is that the American military is not covering this up. It is on CNN and even the military is asking why did this happen. Now I hear there were 2 planes and the guy that did it is a Major with code name "Psycho".
Hope he gets at least demoted or kicked out with a dishonarable discharge.
