Columbus Police say theyâve traditionally fought prostitution with undercover cops arresting prostitutes . But thatâs changing. âWe werenât solving the problem as it was before," says Lt. Mark Lang. "Weâd been doing the same thing for the past 80 years, but it really wasnât making a difference.â? So, Lt. Lang says, theyâre increasing targeting "johns", or men who solicit prostitutes. In one month Lang says itâs proven so effective theyâll spend as much time targeting customers as they do prostitutes. Lang says johns can face jail time, but itâs much more effective to send them to the prosecutorâs âjohn schoolâ? that teaches them about the social issues behind prostitution and its affect on women.
