Can anyone explain why gas prices have risen so much lately even though there is no shortage of oil?

OPEC increased production just in case the events in Libya affected their marginal 2% of the world's production, and it has had no effect on the price of oil. Basically it looks like an excuse to raise the prices and fleece the world. Any reasonable answers out there? Also, why has the media remained complacent and not done anything more than report rising cost without real question?
