This scenario would be like going to a mechanic who quotes you an outrageous price for fixing your car, and, when you begin to question whether it's justified, he tells you that, if you keep asking him questions, he's going to raise his price even more.
Actually it's more like someone who knows a mechanic who has been charging to replace parts that didn't need to be replaced. People who are selling something that isn't honest don't like investigations. If there is no anti-competitiveness to find the DOJ investigation can't have any effect on rates.
