Just watched an interesting documentary, "A Crude Awakening - The Oil Crash". Was very interesting, and kinda joins the dots between the variety of activities we've all seen, and the discussed speculations about motives.
I got it from RARBG, but there are alternative locations. It appears to be well researched, and the interviewees appear to be legitimate. It certainly makes you think.
