Electronic tagging is a form of surveillance that uses an electronic device affixed to a person.

Contents

In some jurisdictions, an electronic tag fitted above the ankle is used for people as part of their bail or probation conditions. It is also used in healthcare settings and in immigration contexts. Electronic tagging can be used in combination with the global positioning system (GPS), but for short-range monitoring of a person that wears an electronic tag, radio frequency technology is used.

History

The electronic monitoring of humans found its first commercial applications in the 1980s. Portable transceivers that could record the location of volunteers were first developed by a group of researchers at Harvard University in the early 1960s. The researchers cited the psychological perspective of B. F. Skinner as underpinning for their academic project. The portable electronic tag was called behavior transmitter-reinforcer and could transmit data two-ways between a base station and a volunteer who simulated a young adult offender. Messages were supposed to be sent to the tag, so as to provide positive reinforcement to the young offender and thus assist in rehabilitation. The head of this research project was Ralph Kirkland Schwitzgebel and his twin brother collaborator, Robert Schwitzgebel (family name later shortened to Gable). [1] [2] The main base-station antenna was mounted on the roof of the Old Cambridge Baptist Church; the minister was the dean of the Harvard Divinity School. [2] [3]

Reviewers of the prototype electronic tagging strategy were sceptical. In 1966, the Harvard Law Review ridiculed the electronic tags as Schwitzgebel Machine and a myth emerged, according to which the prototype electronic tagging project used brain implants and transmitted verbal instructions to volunteers. The editor of a well-known U.S. government publication, Federal Probation, rejected a manuscript submitted by Ralph Kirkland Schwitzgebel, and included a letter which read in part: "I get the impression from your article that we are going to make automatons out of our parolees and that the parole officer of the future will be an expert in telemetry, sitting at his large computer, receiving calls day and night, and telling his parolees what to do in all situations and circumstances [...] Perhaps we should also be thinking about using electronic devices to rear our children. Since they do not have built-in consciences to tell them right from wrong, all they would have to do is to push the 'mother' button, and she would take over the responsibility for decision-making." [4] Laurence Tribe in 1973 published information on the failed attempts by those involved in the project to find a commercial application for electronic tagging. [5]

In the U.S., the 1970s saw an end of rehabilitative sentencing, including for example discretionary parole release. Those found guilty of a criminal offense were sent to prison, leading to sudden increase in the prison population. Probation became more common, as judges saw the potential of electronic tagging, leading to an increasing emphasis on surveillance. Advances in computer-aided technology made offender monitoring feasible and affordable. After all, the Schwitzgebel prototype had been built out of surplus missile tracking equipment. [6] A collection of early electronic monitoring equipment is housed at the National Museum of Psychology in Akron, Ohio. [7]

The attempt to monitor offenders became moribund until, in 1982, Arizona state district judge, Jack Love, convinced a former sales representative of Honeywell Information Systems, Michael T. Goss, to start a monitoring company, National Incarceration Monitor and Control Services (NIMCOS). [8] The NIMCOS company built several credit card-sized transmitters that could be strapped onto an ankle. [9] The electronic ankle tag transmitted a radio signal every 60 seconds, which could be picked up by a receiver that was no more than 45 metres (148 ft) away from the electronic tag. The receiver could be connected to a telephone, so that the data from the electronic ankle tag could be sent to a mainframe computer. The design aim of the electronic tag was the reporting of a potential home detention breach. [10] In 1983, judge Jack Love in a state district court imposed home curfew on three offenders who had been sentenced to probation. The home detention was a probation condition and entailed 30 days of electronic monitoring at home. [11] The NIMCOS electronic ankle tag was trialed on those three probationers, two of whom re-offended. Thus, while the goal of home confinement was satisfied, the aim of reducing crime through probation was not. [12]

Additional technologies

Sweat alcohol content monitor

According to Alcohol Monitoring Systems (AMS), Secure Continuous Remote Alcohol Monitoring (SCRAM) is currently available in 35 U.S. states. [13]

On 31 March 2021, in England, so-called sobriety tags started being rolled out for some offenders who commit alcohol-related crimes after testing the tags in Wales in October of the previous year. It monitors sweat samples every 30 minutes and alerts the probation service if alcohol is detected. [14]

Non-justice-system uses

Medical and health

The use of electronic monitoring in medical practice, especially as it relates to the tagging of the elderly and people with dementia, has generated controversy and media attention. [15] Elderly people in care homes can be tagged with the same electronic monitors used to keep track of young offenders. For people suffering from dementia, electronic monitoring might be beneficially used to prevent them from wandering away. [15] The controversy regarding medical use relates to two arguments, one about the safety of the patients and the other about their privacy and human rights. [16] At over 40%, there is a high prevalence of wandering among patients with dementia. Of the several methods deployed to keep them from wandering, it is reported that 44% of wanderers with dementia have been kept behind closed doors at some point. [17] Other solutions have included constant surveillance, use of makeshift alarms and, the use of various drugs that carry the risk of adverse effects. [16]

Commercial

Smartphones feature location-based apps to use information from global positioning system (GPS) networks to determine the phone's approximate location. [18]

Parental

A company in Japan has created GPS-enabled uniforms and backpacks. [19] School children in distress can hit a button on electronic devices in their uniforms or backpacks, immediately summoning a security agent to their location.[ citation needed ]

Vehicular

Public transport vehicles are outfitted with electronic monitoring devices that communicate with GPS systems, tracking their location. App developers have integrated this technology with mobile apps. Now, passengers are able to receive accurate public transit timetables. [20]

Effectiveness

The use of ankle bracelets, or other electronic monitoring devices, have proven to be effective in research studies and possibly deter crime. [21]

Several factors have been identified as necessary to render electronic monitoring effective: appropriately selecting offenders, robust and appropriate technology, fitting tags promptly, responding to breaches promptly, and communication between the criminal justice system and contractors. The Quaker Council for European Affairs thinks that for electronic monitoring to be effective, it should serve to halt a developing criminal career. [22]

The National Audit Office in England and Wales commissioned a survey to examine the experiences of electronically monitored offenders and the members of their family. The survey revealed that there was common agreement among survey respondents that electronic monitoring was a more effective punitive measure than fines, and that it was generally more effective than community service. An interviewed offender is credited with saying: "You learn more about other crimes [in prison] and I think it gives you a taste to do other crimes because you've sat listening to other people." [23]

In 2006, Kathy Padgett, William Bales, and Thomas Bloomberg conducted an evaluation of 75,661 Florida offenders placed on home detention from 1998 to 2002, [21] in which only a small percentage of these offenders was made to wear an electronic monitoring device. Offenders with electronic tagging were compared to those on home detention without. The factors thought to influence the success or failure of community supervision, including type of electronic monitoring device used and criminal history, were measured. [24] The results showed that offenders who wore electronic tags were both 91.2 percent less likely to abscond and 94.7 percent less likely to commit new offenses, than unmonitored offenders. [24]

Criticisms

The electronic monitoring of a person, on whom an electronic tag is fitted, does not physically restrain this person from leaving a certain area, nor does it prevent this person from re-offendingthe primary aim of probation. Furthermore, the public perception of home detention is that it is a form of lenient punishment. [25]

In the US in 1990, Ronald Corbett and Gary T. Marx criticized the use of electronic monitoring in a paper presented at the Annual Meeting of the American Society of Criminology, Baltimore. In the paper, which was later published in the Justice Quarterly, the authors described 'the new surveillance' technology as sharing some ethos and the information-gathering techniques found in maximum-security prisons thereby allowing them to diffuse into the broader society. They remarked that 'we appear to be moving toward, rather than away from, becoming a "maximum-security society". [26] The authors acknowledged the data mining capacity of electronic monitoring devices when they stated that "data in many different forms, from widely separated geographical areas, organizations, and time periods, can easily be merged and analyzed". [26]

In 2013, it was reported that many electronic monitoring programs throughout the US were not staffed appropriately. [27] George Drake, a consultant who worked on improving the systems said "Many times when an agency is budgeted for electronic-monitoring equipment, it is only budgeted for the devices themselves". He added that the situation was 'like buying a hammer and expecting a house to be built. It's simply a tool, and it requires a professional to use that tool and run the program.' Drake warned that programs can get out of control if officials do not develop stringent protocols for how to respond to alerts and do not manage how alerts are generated: "I see agencies with so many alerts that they can't deal with them," Drake said. "They end up just throwing their hands up and saying they can't keep up with them." In Colorado, a review of alert and event data, obtained from the Colorado Department of Corrections under an open-records request, was conducted by matching the names of parolees who appeared in that data with those who appeared in jail arrest records. The data revealed that 212 parole officers were saddled with the duty of responding to nearly 90,000 alerts and notification generated by electronic monitoring devices in the six months reviewed. [27]

Notable instances

Jurisdictions

United Kingdom

Those subject to electronic monitoring may be given curfews as part of bail conditions, sentenced under the Criminal Justice Act 2003 in England and Wales (with separate legislation applying in Scotland). Alternatively offenders may be released from a prison on a Home Detention Curfew. Released prisoners under home detention are allowed out during curfew hours only for:

Additionally, electronic monitoring may be used for those subject to a curfew given under the Terrorism Prevention and Investigation Measures Act 2011 (previously known as a control order under the Prevention of Terrorism Act 2005 [34] )

Since electronically monitored curfews were rolled out throughout England and Wales their use has increased sharply, from 9,000 cases in 1999–2000 to 53,000 in 2004–05. In 2004–05, the Home Office spent £102.3 million on the electronic monitoring of curfews and electronically monitored curfews are considered cheaper than custody. [35]

Typically, offenders are fitted with an electronic tag around their ankle which sends a regular signal to a receiver unit installed in their home. Some systems are connected to a landline in the case where GSM is not available, whilst most arrangements utilize the mobile phone system to communicate with the monitoring company. If the tag is not functioning or within range of the base station during curfew hours, or if the base is disconnected from the power supply, or the base station is moved then the monitoring company are alerted, who in turn, notify the appropriate authority such as the police, the National Probation Service or the prison the person was released from. [36]

In 2012, the Policy Exchange think tank examined the use of electronic monitoring in England and Wales and made comparisons with technologies and models seen in other jurisdictions, particularly the United States. The report was critical of the Ministry of Justice's model of a fully privatized service - which gave little scope for police or probation services to make use of electronic monitoring. The report, Future of Corrections, also criticized the cost of the service, highlighting an apparent differential between what the UK taxpayer was charged and what could be found in the United States. [37]

Subsequently, there were a number of scandals in relation to electronic monitoring in England and Wales, with a criminal investigation opened by the Serious Fraud Office into the activities of Serco and G4S. [38] As a result of the investigation, Serco agreed to repay £68.5 million to the taxpayer and G4S agreed to repay £109 million. [39] The duopoly were subsequently stripped of their contract, with Capita taking over the contract. In 2017, another criminal investigation saw police make a number of arrests in relation to allegations that at least 32 criminals on tag had paid up to £400 to Capita employees in order to have 'loose' tags fitted, allowing them to remove their tags. [40]

The monitoring of sex offenders via electronic tagging is currently in debate due to certain rights offenders have in England and Wales. [41]

Electronic tagging has begun being used on psychiatric and dementia patients, prompting concern from mental health advocates who state that the practice is demeaning. [42]

In June 2022, the British Home Office announced a one-year pilot to track migrants who arrived on small boats on "dangerous and unnecessary routes" with GPS devices that will help "maintain regular contact" and more "effectively process their claims". [43]

Australia and New Zealand

In Australia and New Zealand existing law permits the use of electronic monitoring as condition for bail, probation or parole. But, according to the 2004 Standard Guidelines for Corrections in Australia the surveillance must be proportionate to the risk of re-offense. It is also required that, the surveillance of the offender is minimally intrusive for other people who live at the premises. Electronic tagging of a person is part of different electronic monitoring systems in Australia. Correctional agency statistics are collected in Australia for so called "restricted movement orders". In South Australia, a drive-by facility allows the monitorer to drive past a building in which the tagged person is supposed to be. [44]

In New Zealand, the electronic tagging of offenders began 1999, when home detention could be imposed instead of imprisonment. [45] By late July 2023, Stuff reported that 2,230 teenagers had been subject to electronic monitoring since 2019, citing figures released by the Department of Corrections. The number of 13 year olds wearing ankle bracelets rose from one in 2019/2020 to nine in 2022/2023. The vast majority teenagers subject to electronic monitoring were males, with 2,011 reported in July 2023. [46]

Brazil

In August 2010, Brazil awarded a GPS Offender Monitoring contract to kick start its monitoring of offenders and management of the Brazilian governments early release programme. [47]

South Africa

Electronic monitoring as a pilot project was started in March 2012, involving 150 offenders, mostly prisoners serving life terms. The project was rolled out to reduce the South Africa's prison population. It consequently would also reduce the taxpayer's burden on correctional facilities. [48] South Africa locks up more people than any other country on the continent. [48]

A rehabilitation policy within criminology, is one intending to reform criminals rather than punish them and/or segregate them from the greater community.

The New Zealand Parole Board is an independent statutory body established in 2002 that considers offenders for parole. Its task "is to undertake an assessment of the risk that long-term sentenced offenders might pose to the safety of the community if they were to be released before the end of their sentence". The Board also sets conditions of release for offenders so their reintegration back in to the community can be effectively managed. Once the conditions are set it becomes the responsibility of Community Corrections to manage the offender." 'Long term' is defined as more than 24 months. Short-term prisoners are automatically released after serving half their sentence.

The New Zealand Probation Service is a branch or service of the New Zealand Corrections Department. Established in 1886, its role is to manage offenders sentenced to community based sentences such as home detention, community detention and intensive supervision. The Service also manages prisoners in the community who have been released on parole and offenders on release conditions at the end of their prison sentence. According to Corrections website, in 2014 the Service was looking after approximately 30,000 offenders in the community. The Probation Officer's role is described as "work(ing) with people on probation to motivate them to make changes in their lives. This may include attending programmes to address violence, alcohol and drug abuse or driving offences."

<span class="mw-page-title-main">Lifetime probation</span>

Lifetime probation is reserved for relatively serious legal offenders. The ultimate purpose of lifetime probation is to examine whether offenders properly maintain good behavior as well as capability of patience under lifetime probation serving circumstance. An offender is required to abide by particular conditions for rest of their entire life in order to nurture superior social behaviour as a punishment for their criminal offence. Condition of probation orders contain supervision, electronic tagging, reporting to his or her probation or parole officer, as well as attending counselling. The essential component of lifetime probation carries the sense of being examined for well-being character and behaviour for life term period. Legislative framework regarding probation may vary depending on the country or the state within a certain country as well as the duration and condition of probational sentencing.

<span class="mw-page-title-main">Decarceration in the United States</span> Overview article

Decarceration in the United States involves government policies and community campaigns aimed at reducing the number of people held in custody or custodial supervision. Decarceration, the opposite of incarceration, also entails reducing the rate of imprisonment at the federal, state and municipal level. As of 2019, the US was home to 5% of the global population but 25% of its prisoners. Until the COVID-19 pandemic, the U.S. possessed the world's highest incarceration rate: 655 inmates for every 100,000 people, enough inmates to equal the populations of Philadelphia or Houston. The COVID-19 pandemic has reinvigorated the discussion surrounding decarceration as the spread of the virus poses a threat to the health of those incarcerated in prisons and detention centers where the ability to properly socially distance is limited. As a result of the push for decarceration in the wake of the pandemic, as of 2022, the incarceration rate in the United States declined to 505 per 100,000, resulting in the United States no longer having the highest incarceration rate in the world, but still remaining in the top five.

Electronic monitoring or electronic incarceration (e-carceration) is state use of digital technology to monitor, track and constrain an individual's movements outside of a prison, jail or detention center. Common examples of electronic monitoring of individuals under pre-trial or immigrant detention, house arrest, on probation or parole include: GPS wrist and ankle monitors, cellphones with biometric security systems, ignition interlock devices and automated probation check-in centers or kiosks.
