That may be true when they are truly "scalp hunting", but we "drones" are the ones that have to meet with them, answer their questions, and justify our answers.
Given the chance, production will do anything they can to get product out the door, good or bad. I've experienced it in every industry in which I've been involved (automotive, plumbing products, and pharmaceuticals.) QA is always left to clean up their mess, usually with a comment from upper management of "why didn't you catch that?"
Root cause: QC didn't catch it.
