Every year in the run-up to Halloween, Patch publishes maps showing the homes of “registered sex offenders” in various cities. Ostensibly, this information is aimed at helping parents who worry that their children might be molested while trick-or-treating. But research shows that such fears have no basis in reality, and these stories—like the warning signs and restrictions imposed by local police prior to Halloween—mainly serve to stigmatize people who have already completed their sentences, along with their spouses and children, who have committed no crimes at all. That stigma invites harassment, vandalism, and violence. Like much local journalism, the practice of publishing these maps is ill-informed sensationalism masquerading as a public service.
