I agree there needed to be better safeguards . A disaster like this was being said to be impossible by BP a few weeks ago also. A similar spill in Santa Barbara in 1969 ended coastal drilling on the West coast. Drilling in the Gulf will also change as a result of this disaster. Business as usual is going to have to change.The following is the best article I've found regarding this mess to date.
