The Joker began his second stage in the 1950s. In this stage, Joker committed comical themed robberies. He did not kill anyone. This is due to the Comics Code Authority. In 1956, the Comics Code Authority came in to power, and halted the Joker’s murderous ways (www.comicartville.com... ). General standards, part A, rule 9, states that, “Instances of law enforcement officers dying as a result of a criminal's activities should be discouraged.” The Joker killed a judge in his first comic book appearance. The Comic Code used this rule to prevent the public from thinking that criminals could ever defeat the law. Rule 5 states that, “Criminals shall not be presented so as to be rendered glamorous or to occupy a position which creates the desire for emulation.” The Code saw Joker as too offensive and he, like many comics, was a cause for juvenile delinquency (“The Joker’s Dozen,” 7).
“The Joker Jury” best shows the Joker’s second stage. The Joker stages crimes that are based on Gotham city’s departments. He sends a clue to Batman saying that he will “use my (Joker’s) own sanitation department” to commit his next robbery (Kahn 147). He then uses a giant vacuum cleaner to “clean up” a precious gem exhibit. He does not kill anyone in the process.
