I was watching an old History Channel piece last night about comic book superheros. The show traced the development of comic books through the introduction of Superman, use of super heros helping the war effort and taking on social issues of the 60's and later decades.
One particular part caught my attention; the show was elaborating about the evolution of Batman and how in later years DC comics used the character as a commentary on the hot political issues of the day (early 90's). DC's publishers were approached to address gun control/crime/violence.
They willingly obliged and printed a "one-shot" issue of Batman called "The Seduction of the Gun" (the plot has something to do with gang-bangers buying guns in Virginia and reselling them in the Hood).
Some of the artwork they showed had teenage gang types running around shooting off TEC-9s, MACs and other "full-auto" VPC favorites).
Allegedly, the printing had some small part in getting a gun-control bill passed (from Googling around, I think it might have been Virginias "one gun a month" law).
