Here is what happens when they do.
Read this article by Greg Palast from Truthout.org. Here are some excerpts:
"To contain a spill, the main thing you need is a lot of rubber, long skirts of it called a "boom." Quickly surround a spill, leak or burst, then pump it out into skimmers, or disperse it, sink it or burn it. Simple."
"...BP has figured out a very low-cost way to prepare for this task: BP lies. BP prevaricates, BP fabricates and BP obfuscates."
EXXON VALDEZ SPILL
" I was a fraud investigator hired to dig into the cause of the Exxon Valdez disaster. Despite Exxon's name on that boat, I found the party most to blame for the destruction was ... British Petroleum (BP).""Before the Exxon Valdez grounding, BP's Alyeska group claimed it had these full-time, oil spill response crews. Alyeska had hired Alaskan natives, trained them to drop from helicopters into the freezing water and set booms in case of emergency. Alyeska also certified in writing that a containment barge with equipment was within five hours sailing of any point in the Prince William Sound. Alyeska also told the state and federal government it had plenty of boom and equipment cached on Bligh Island.
But it was all a lie. On that March night in 1989 when the Exxon Valdez hit Bligh Reef in the Prince William Sound, the BP group had, in fact, not a lick of boom there. And Alyeska had fired the natives who had manned the full-time response teams, replacing them with phantom crews, lists of untrained employees with no idea how to control a spill. And that containment barge at the ready was, in fact, laid up in a drydock in Cordova, locked under ice, 12 hours away."
DEEPWATER HORIZON SPILL
"Where was BP's containment barge and response crew? Why was the containment boom laid so damn late, too late and too little? Why is it that the US Navy is hauling in 12 miles of rubber boom and fielding seven skimmers, instead of BP?"
"...the spill response crews were told they weren't needed because the company had already sealed the well. Like everything else from BP mouthpieces, it was a lie."
WHY DID IT HAPPEN?
"Americans want government off our backs ... that is, until a folding crib crushes the skull of our baby, Toyota accelerators speed us to our death, banks blow our savings on gambling sprees and crude oil smothers the Mississippi.
Then, suddenly, it's, "Where was hell was the government? Why didn't the government do something to stop it?"
"It was only last month that BP, lobbying for new deepwater drilling, testified to Congress that additional equipment and inspection wasn't needed."
"...one of the platform workers has informed him that the BP well was apparently deeper than the 18,000 feet depth reported. BP failed to communicate that additional depth to Halliburton crews, who, therefore, poured in too small a cement cap for the additional pressure caused by the extra depth. So, it blew."
"BP says its worker is lying. Someone's lying here, man on the platform or the company that has practiced prevarication from Alaska to Louisiana. "
