This week we speak to Mark Nelson, a car mechanic and father of five, who has been forced to wear a GPS tag by the Home Office for the past 20 months, and his lawyer Katie Schwarzmann of Wilsons Solicitors. The pair have been challenging the Home Office's ongoing imposition of GPS tracking on Mark in the courts and are now awaiting a judgement. We explore the legal case, the ways the tag hasn't worked for long periods of time, and a dubious AI the Home Office has been using in decisions as to whether someone remains on a GPS tag.
