From behind the wheel of his hulking GMC Suburban, 76-year-old Otis McDonald leads a crime-themed tour of his Morgan Park, Illinois, neighborhood. He points to the yellow brick bungalow he says is a haven for drug dealers. Down the street is the alley where five years ago he saw a teenager pull out a gun and take aim at a passing car. Around the corner, he gestures to the weed-bitten roadside where three thugs once threatened his life. "I know every day that I come out in the streets, the youngsters will shoot me as quick as they will a policeman." McDonald was recruited by gun-rights advocates to lead a suit challenging Chicago's handgun ban that will be argued before the Supreme Court Tuesday.
