This cartoon by Clay Bennett from the Chattanooga Times Free Press shows NRA executive vice president Wayne LaPierre being handcuffed and arrested by a policeman. An automatic weapon lies on the ground, so we can suppose that LaPierre has broken the law in some way.
Following the Sandy Hook Elementary School massacre in December, LaPierre held a press conference during which he called on Congress to pass a law putting armed police officers in every school in America, saying, "The only thing that stops a good bad guy with a gun is a good guy with a gun." The cartoonist clearly thinks that LaPierre himself is the bad guy for championing the right to possess deadly weapons. The policeman represents the good guy, i.e., gun control.
