Peter Parker: The Spectacular Spider-Man #71 (1982) First Print

WITH THIS GUN... I THEE KILL! When two kids try to rob a grocery with illegal guns, Spider-Man is there to try and stop them, however, the shop owner is also armed and shoots one of the thieves dead. Later when turning over pictures to the Bugle, Peter hears J. Jonah Jameson talking about a tip-off of a shipment of illegal weapons.  Peter goes into action as Spider-Man and tries to stop the shipment, however, a police officer is killed in the line of duty in spite of Spider-Man helping stop the operation. When Peter goes to turn in his pictures to the Bugle, he's a little more than disgusted by Lance Bannon's suggestion that Peter should get a Pulitzer, and considers that the widow of the officer killed will only be getting a posthumous medal. It's a bitter victory for stopping gun crime, as Jameson comes in and tells them that even though there was this huge bust, there were still 12 reported shootings in the city that night.
