For the most part, I agree that this discussion is mostly academic. They are not likely to even ask how the power supply was being used in any return. If it is a failure due to materials and/ or workmanship, then it should be repaired under warranty regardless of intended use.
The statement about lying to a police officer is going too far though. Having served on a grand jury in Georgia, I will tell you that providing false information to a police officer is a crime in Georgia - I think it's just a misdemeanor, but one event can generate a lot of violations. Take the fifth and say nothing if you like, act totally clueless/ignorant of any wrongdoing, but do not tell an outright lie.
Striking a police officer or teacher is a felony.
Failure to follow the lawful command of a police officer is a misdemeanor.
