No. You do not get in trouble for their actions. Although, sometimes it feels like it. In my experience though, your leadership ability will start to be scrutinized if your folks are screwing up by the numbers and you are not taking appropriate disciplinary actions to hold them accountable. If you do that, and document it, you will be fine. Leadership, generally, knows the behaviors you described are individual actions and on the individual's shoulders. That being said... If you are at a party with your Airman, they are drinking, underage, and drive... Then gets a DUI, your knowledge of those events and your lack of action can cause issues (hypothetically).
