Have you noticed that Cheney hasn't worked for Halliburton for a decade?
I know he hasn't, but it sure is fun to take jabs at him!!
Unfortunately for your attempted jab, Halliburton wasn't involved with this incident. Therefore, your jab doesn't come across as funny, let alone relevant. Maybe next time....
You might wish to check the news. Halliburton was the subcontractor responsible for the pouring of the cement at the well. It may well be that they didn't do anything that contributed to this disaster, but they certainly were involved.
