Gas Prices

We always see the price of gas soar and they always blame it one reason or another. Something happens and almost overnight the price of gas is raised. However, have you ever noticed that when the reason given is resolved that we don't see the prices lower so drastically or quickly? Usually we don't ever see it lower to the price it was before. This tells me that they just look for any excuse to raise the price of gas so they can retain a residual higher price in the end.
