Man buys gift for friends on Amazon—a headlamp. It’s defective; it burns down his friends’ Montgomery County, Md. home. Must Amazon pay the friends’ insurer? The Fourth Circuit says no; under state law, Amazon is not a “seller” as it never took title to the lamp. Concurrence: Which is about the only thing Amazon didn’t do; it warehoused the lamp, took payment for it, and assumed the risk of credit card fraud, among things. Maryland legislators and judges might want to look into this.
