It is illegal to walk down the street carrying a violin in a paper bag.

The Law Explained

A bizarre piece of Covington legislation forbids anyone from carrying a violin concealed in a paper bag while walking down public streets. The rumor suggests this law was passed during Prohibition or a period of mob violence, where criminals would hide small firearms or illicit booze in oddly shaped instrument bags. Authentic musicians had to use proper hard cases to avoid police suspicion.
