John, James, Jaion and Harry are being monitored by the latest tagging technology. They are 4 of the 14,000 people currently on electronic tag, a number the government wants to double by 2025. James and Jaion are on GPS tags, which track their movements 24 hours a day and alert the police if they enter their ‘exclusion zones'. John and Harry are on alcohol abstinence tags, which sample their sweat every 30 minutes and alert probation if they break their drinking bans. All four face prison if they don't stick to their tag orders, but with family pressures, addiction issues and Covid delays in the court system, is being on tag enough to keep them out of trouble?
