Prices rise, during panic buying. There WAS isolated panic buying.
Since you are unaware of the fact that Katrina hit the port in New Orleans, please let me inform you that it did. Drilling and refining has been shut down. The flow of oil has been disturbed. When supply is disrupted, of ANY commodity, the price rises. When there is a glut, the price falls.
When our government imposes caps on prices, the commodity falls.
And FYI.....the net rule is, that when someone uses Hitler or Nazi, in a debate, as refutation, that person immediately loses. CONGRATS on your "uber alles" loss! :-)
