Finally gotten around to do a little investigation

You can check out second article posted in the link.
You can google 'halliburton' and 'businessweek' which the magazine is owned by the mcgraw-hill companies, whose stock is controlled by halliburton. Most of the article written on halliburton is approved and published by mcgraw-hill who would never, ever put them in a negative light and alway march their orders. Will look into it more later on
