I can’t help but notice the scene in season 2, where Walter Jr. attempts to buy alcohol. His friends ask him to approach a man, outside of a gas station, and ask if he would mind buying them some alcohol. This gentleman turns out to be an off-duty cop.
The scene that shortly followed is Walter Jr. being picked up by Hank. We are assuming that this gentleman was informed of Hank’s position by Walter Jr. Hank is high up the ranks, but not too high, really. Does he have the power to not allow any charges to be pressed on the crime? For me, it was in and out that scene, too quickly.
