The government regulatory agency could have demanded that the latest shut-off devices be required, but they are not insisted upon in U. S. offshore drilling (see previous posts- but I understand Haliburton has put them on Norwegian offshore drillers.

A question in my mind-
This well, and two more like it drilled by BP are some 35,000 feet to source; water depth is great and this one entered a formation with very high pressure, apparently not predicted. Just how safe is drilling given these conditions ?

Crist and Swartzenegger are backing away from their call for offshore drilling.
Rubio points to the many Gulf offshore wells that have been completed successfully, but few were to this depth, in this depth of water, or encountered high pressure under these conditions. He seems to be comparing fleas to elephants.
