Ankle Bracelets: Monitoring Criminals And Their Movements

Ankle bracelets, also known as ankle monitors, are electronic devices affixed to a person's ankle to monitor their location and movement. They are typically used as a condition of bail, probation, or parole, and can be combined with GPS technology or radio frequency for tracking. Ankle bracelets have also been used in healthcare settings, immigration contexts, and to monitor alcohol consumption and sweat samples. While they are intended to reduce crime and ensure compliance with court orders, there are concerns about their effectiveness, impact on civil liberties, and potential for stigmatization.

Ankle bracelets monitor location via GPS

Ankle bracelets are increasingly being used as a form of electronic surveillance to monitor the location of individuals via GPS. This technology is often used as an alternative to incarceration, allowing non-violent offenders to serve their sentences outside of traditional correctional facilities. By leveraging GPS technology, ankle bracelets provide authorities with real-time location tracking capabilities, enabling them to supervise individuals effectively and enhance community safety.

A GPS ankle bracelet typically consists of a GPS module, a cellular module for data transmission, and a secure electronic strap. These components work together to ensure accurate and reliable tracking. The GPS module receives signals from multiple GPS satellites, calculating the distance between the wearer and each satellite through trilateration to determine their precise location. This location data is then transmitted in real-time to monitoring stations via cellular networks.

One example of a GPS ankle bracelet is the SCRAM GPS®, which offers superior location accuracy, long battery life, and user-friendly software tools. SCRAM GPS provides location monitoring for sex offenders, violent offenders, and domestic violence cases, helping officers supervise clients effectively. It also features geo-fencing, allowing for the creation of virtual boundaries, with alerts triggered if an individual violates a predefined zone.

While GPS ankle bracelets offer benefits such as reduced jail overcrowding and rehabilitation opportunities, they also raise privacy concerns. It is crucial to implement these devices within a legal framework that ensures privacy protection and data security. Additionally, factors such as environmental conditions and signal interference may impact the accuracy of GPS tracking.

In conclusion, ankle bracelets that monitor location via GPS have become a common tool in the justice system, providing authorities with a means to supervise individuals without the need for physical incarceration. While offering benefits such as reduced jail overcrowding and improved community safety, it is essential to address privacy concerns and accuracy limitations to ensure fair and effective monitoring practices.

They can be used to monitor alcohol consumption

Ankle bracelets are used to monitor alcohol consumption by testing the wearer's perspiration for alcohol every 30 minutes. This is known as transdermal alcohol testing. The bracelets are typically worn for 30, 60, or 90 days and are often court-ordered for those convicted of driving under the influence (DUI) or other alcohol-related offences. They are also used in family court, domestic violence cases, underage drinking cases, and substance abuse cases.

The Secure Continuous Remote Alcohol Monitoring (SCRAM) bracelet is an example of an alcohol-monitoring ankle bracelet. It provides 24/7 alcohol testing and is said to increase compliance with court orders and enhance community safety. The SCRAM bracelet can distinguish between alcohol consumption and exposure to external environmental sources of alcohol, such as alcohol-based products. It also has temperature and infrared sensors that can detect attempts to tamper with or obstruct the device.

The data collected by the SCRAM bracelet is transmitted wirelessly to a base station and then uploaded to monitoring software, where it is analysed by trained professionals. If the wearer is not in range of the base station, the bracelet will continue to gather information and transmit readings once back in range. This allows for minimal disruption to the wearer's daily life, as they can still shower, work out, and carry out everyday activities.

The cost of alcohol monitoring can be significant, with installation fees ranging from $50 to $100 and daily monitoring fees of around $10 to $15, resulting in monthly costs of up to $450 or more. However, studies have shown that wearing a SCRAM bracelet for at least 90 days, combined with alcohol treatment, can reduce the risk of reoffending for those convicted of DUI.

They are used as an alternative to incarceration

Ankle bracelets, also known as ankle monitors, are used as an alternative to incarceration, particularly in the case of those awaiting trial, serving probation or parole, or facing immigration proceedings. They are often used as a condition of bail or probation, allowing individuals to be monitored while living in the community instead of being held in jail or prison. This form of electronic monitoring typically involves GPS tracking to record the location of the wearer, with some jurisdictions also implementing curfews and restricted movement orders.

The use of ankle bracelets as an alternative to incarceration has been promoted as a way to reduce prison populations and the associated costs, as well as to enhance community safety by allowing officers to supervise individuals more effectively. This method of monitoring is particularly useful for high-risk clients requiring around-the-clock location monitoring, such as sex offenders, violent offenders, and domestic violence cases. By providing real-time location data, officers can quickly identify and address any issues that may arise with the individuals under their supervision.

In addition to GPS tracking, ankle bracelets can also be equipped with alcohol monitoring capabilities, particularly for drunk driving and domestic violence cases. These devices sample the wearer's perspiration every 30 minutes to detect alcohol consumption, providing accountability and encouraging compliance with court orders. This form of continuous alcohol monitoring has been shown to support long-term behaviour change and increase sobriety rates, making it a valuable tool in treatment and rehabilitation programmes.

While the use of ankle bracelets can provide certain benefits, it is important to consider potential drawbacks and negative impacts on the wearers. The stigma, social isolation, and stress associated with being monitored can exacerbate mental health issues such as depression and anxiety. Additionally, the fees associated with wearing these devices can be burdensome, particularly for individuals and families already facing financial challenges due to incarceration. Furthermore, the restrictions on movement can hinder individuals' ability to work, attend school, or access necessary services, ultimately impacting their ability to successfully reintegrate into society.

They are used to monitor people on bail, probation, or parole

Ankle bracelets, also known as ankle monitors, are a form of electronic surveillance used to monitor people on bail, probation, or parole. They are typically fitted above the ankle and use GPS technology or radio frequency to track the wearer's location. This allows authorities to ensure that individuals are adhering to their bail, probation, or parole conditions, including curfews and restricted movement orders.

In the context of bail, ankle bracelets are often used as an alternative to incarceration, allowing individuals awaiting trial to remain in their communities while their case is pending. This measure aims to reduce prison populations and provide a less restrictive form of supervision. For those on probation or parole, ankle bracelets help authorities monitor compliance with court orders and enhance community safety.

The use of ankle bracelets for bail, probation, or parole carries several implications. On the one hand, it offers a level of supervision and accountability, potentially reducing the likelihood of reoffending. Studies have shown that monitored individuals are less likely to abscond or commit new offences compared to unmonitored offenders. However, the use of ankle bracelets has also been criticised for its potential to infringe on privacy and freedom of movement, leading to social isolation and stigma.

Ankle bracelets are just one component of electronic monitoring programmes, which may also include alcohol monitoring, house arrest, or curfews. These programmes aim to provide a comprehensive approach to community supervision and often involve regular check-ins with supervising officers. While electronic monitoring offers an alternative to traditional incarceration, it has faced scrutiny for its potential to contribute to mass incarceration, particularly for minor technical violations related to the ankle bracelet.

In addition to their use in the criminal justice system, ankle bracelets have also been employed in immigration contexts and healthcare settings, particularly for individuals with dementia or Alzheimer's disease. However, their use in these contexts has sparked debates around safety, privacy, and human rights.

They can be used to monitor people facing immigration proceedings

Ankle bracelets are used to monitor people facing immigration proceedings. In the US, the Intensive Supervision Appearance Program (Isap) uses ankle monitors, voice recognition, or a tracking app to surveil immigrants. The program is run by private contractor BI Inc. on behalf of US Immigration and Customs Enforcement (Ice).

Isap was launched in 2004 as an alternative to detention for immigrants awaiting court dates. It is supposed to help immigrants access social services while keeping track of their whereabouts. However, the program has been criticized for its use of painful and bulky ankle monitors that can cause bruising, overheating, and electroshocks. There are also concerns about the lack of transparency and inconsistent decision-making in the program. For example, there is no clear guidance on when to use ankle monitors, and immigrants can end up wearing them for extended periods, ranging from six months to three years.

In addition to the physical discomfort caused by the devices, ankle monitors can also have negative psychological and social impacts. They are visible and can attract unwanted attention, leading to social isolation and stigma. The constant surveillance and arbitrary rules can cause stress, anxiety, and a sense of being treated like a criminal.

The Biden administration has also implemented the Family Expedited Removal Management (FERM) program, which uses ankle bracelets and phones to track migrant families from certain countries who have claimed asylum. The program aims to facilitate quick deportation, and participants are subject to a curfew and regular check-ins with immigration officers.
