An online gun retailer has sparked outrage over the sale of a shooting target based on the likeness of Trayvon Martin, the unarmed black teenager shot dead in Florida earlier this year. The site, GunBroker.com, carried an advertisement from a Florida man offering a paper silhouette depicting a hooded man holding skittles and iced tea — the same items Martin was holding when self-appointment neighborhood watchman George Zimmerman shot him dead. The unidentified seller says he sold out of the targets in two days. They are no longer being listed online.
