I’d like to agree with you but unfortunately Fast and Furious already contains the most important elements of the so-called conspiracy theory and makes extensions of that theory plausible, even if not proven. In other words, it is on the menu of possibilities.
Sadly, I believe the current administration is capable of perpetrating this level of inhumanity. A brief survey of the history of Marxist regimes of the previous century should be enough to convince any rational person that there is a very real risk for the people attracted to such movements to value political goals more highly than innocent human life.
However, like you, I also believe that sometimes bad things, on a large scale, can happen without resort to any secretive explanation. There is such a thing as insanity, and it can occasionally manifest itself in the most painful of ways.
My own principle is to eliminate neither option until more is known. I am curious about the supposed second shooter, for example. That would mitigate against randomness. Or is he the fictional byproduct of the fog of war? Who knows. Time will tell.
