1. "They don't call." Goerge Clooney, in movie "Michael Clayton".
Police don't call, they always knock on your door. If you receive a call from police, 99% of the time it's a prank. In your case, it's probably from the person to whom you sold the CDs.
2. You are NOT to talk to a police officer for any accusation against you. NEVER.
"You have the right to remain silent. Anything you say can and will be used against you in a court of law. You have the right to be speak to an attorney, and to have an attorney present during any questioning. If you cannot afford a lawyer, one will be provided for you at government expense."
Officer: "Sir, do you know why I stopped you?", You: "Sorry, I was speeding." Wrong Answer.
3. Stop wasting everyone's time. Next time use your brain.
