BP knew of cement flaws, why didn't the government inspectors?

Halliburton officials knew weeks before the fatal explosion of the BP well in the Gulf of Mexico that the cement mixture they planned to use to seal the bottom of the well was unstable but still went ahead with the job, the presidential commission investigating the accident said Thursday.

BP cut corners to maximize profits.

Unfortunately, that's what corporations do. It's why we have inspectors.

Where were the government inspectors?

Oh, that's right - - BP's permit applications were approved with minimal review by the administration of Barack Obama, the man who received more donations from BP than any other politician in history.
