Cooper said his office is looking into how to tighten the law that investigators are trying to use against Gibson. That’s the Lacey Act, which bars the purchase of wood and other goods exported in violation of a foreign country’s laws.

“In theory, anybody who travels across the state line with an old guitar is in legal jeopardy,” Cooper, a Democrat, told reporters. “You make all these magnificent instruments unsellable and untransferable and unshippable. The most famous violins in the world are Stradivarius violins. I’m sure all of those violate the law. You can’t sell a Stradivarius violin anywhere. This is just like way too broad.”
