Drug kingpin Joaquin “El Chapo” Guzman, a Houdini-like master of escape accused of running one of the world’s largest drug trafficking organizations, entered a not guilty plea through his attorney at an arraignment Friday in federal court in Brooklyn. The diminutive, clean-shaven trafficker, described by a federal official as “the most notorious criminal of modern time,” was not handcuffed and wore a dark blue short-sleeved shirt and pants with white sneakers during his brief appearance in a packed courtroom.
