...[An] investigative panel heard candid testimony from a widow of a rig worker killed during the April 20th rig tragedy... Her husband worked for TransOcean, which owned the rig and was operating it for BP's drilling project. She accused her husband's supervisors of dwarfing safety concerns to save money... John Guide, a BP Wells Team Leader quickly faced questions from investigator Jason Matthews of the Bureau of Ocean Energy Management... Matthews wanted to know if BP put money ahead of lives Matthews asked Guide, "Do you think that BP did everything they could to manage the risk as low as possible?" Guide replied, "Yes, sir." Though workers from the company Schlumberger were on the rig to conduct a final cement strength test, BP opted against it... But Guide said all of the other indicators showed the well was in good shape.
