Yes, but it would take a great amount of resources to prove it. I work in the financial serverices industry and I find it to be reprehensible what tradres are doing. There was a supposed premium built into oil prices for such a disaster. Now that it has happened they just use it as an excuse to speculate even more. Who profits? The traders and oil companies. Disgusting. For me, I am not buying gas unless I REALLY have to. I refuse to pay these prices. Until people scale back on car usage and taking long and unecessary trips, prices will not go down.
