That's Crap

Before Hurricane Katrina and there was plenty of oil supply, gas prices went up and OPEC said they didn't know why. They said that the prices are set by the trading world market and that the supply didn't reflect that the market value should be so high. They were "dumbfounded" they said. Plenty of oil yet price went up. They said that gas prices at the pump were going up because of the price at which the oil was trading on the world market. Ok have I made that clear enough yet?
After Katrina, gas prices went up because of the lack of supply in the U.S. Ok. Makes sense. Every single time there is any sign of any type of unrest in the middle east, the gas prices go up. Ok ok...whatever. There has been unrest in the middle east for thousands of years. Somebody says or does something today and the price goes up? Whatever. So what part of this is "crap"? Read on.
The oil pipline in Alaska is out of service yet the world market value continues to drop every day yet the gas prices continue to go up. So before when they said that supply didn't have anything to do with it and that our gas prices were determined by the world market value, when the world market value goes DOWN, the gas prices go up? THAT'S CRAP!!
