Not sure where the idea that there were not spills during Katrina came from:
Aug.-Sept., New Orleans, Louisiana:
The Coast Guard estimated that more than 7 million gallons of oil were spilled during Hurricane Katrina from various sources, including pipelines, storage tanks and industrial plants.

Offshore drillling is far from it's peak so you would expect fewer incidents. I don't believe it when the oil industry tells me they have technology that has mitigated the risk. I lived in Houston for 25 yrs up until 4 yrs ago and spent a lot of time on the water. There are still lots of oil dollops floating about and on the beach. I had to keep cleaners in the truck to do my waders and the boat hull after the trip. Hardly pristine.
When it comes to taking care of us, are we really going to believe Exxon and W?
