Since June, an app has allowed survivors, who are overwhelmingly women, to see exactly where their stalker is
On a large screen in a control centre in eastern Seoul, a dot representing a man closes in on a woman. The dot changes direction, and the distance reading between them falls from 845 metres to 792.
On the woman’s phone, the same map is loading. A probation officer rings her: the stalker is approaching, don’t panic, officers have been dispatched. The man is a stand-in and the scenario is staged, but the system is real.
