I think hauling oil exec's in front of the Senate Judiciary Committee was largely just for show. What possible purpose do statements like these have?
"You have to sense what you're doing to us - we're on the precipice here, about to fall into recession," said Sen. Richard Durbin, D-Ill. "Does it trouble any one of you - the costs you're imposing on families, on small businesses, on truckers?"
Its a classic example of reductionism. Reduce a complex problem to one scapegoat and score political points while lashing the goat with emotional rhetoric.
