Alderman Jason Ervin, 36, of the 28th district said the ordinance would ban the convicts from public parks and walkways in zones designated by the police superintendent, the Chicago Sun-Times reported Friday. Advertisement Ervin said prostitution is a major issue in his ward. "Residents there have to pick up used condoms off their lawns," he said. "I don't want my community to look like that. This gives police another tool." The alderman said the ordinance would be similar to the city's anti-gang loitering zones, which ban known gang members from gathering in the specified areas.
