As mentioned earlier, I agree with the view that crime can be suppressed through drug treatment for the subjects. Even though most subjects of the electronic monitoring system wear electronic ankle monitors, in most cases they commit crimes because they fail to suppress a momentary sexual impulse. On this basis, I judge that, even for persons subject to ankle monitors, where a risk of reoffending exists, combining the monitor with the sexual-impulse-suppressing drug treatment currently in force, with the subject's consent or where the subject voluntarily wishes it, would be an effective means of preventing reoffending. I also think that, in Korea as an IT powerhouse, methods using mobile technology can be used. Currently, some areas offer a service that, upon application, informs parents of their child's location by SMS. Through this service, parents can check their children's location at any time. In addition, using smartphone application technology, when a person wearing an ankle monitor comes nearby, the phone could detect this and send the information to the school and the parents, making it possible to block the occurrence of crime at the source. Children would also be able to get help by going to the school security guard or the nearby local police box. Combining these methods at an appropriate level would be an opportunity to develop the electronic monitoring system in a more efficient direction, and furthermore its significance lies in responding proactively in advance rather than with "fixing the barn after losing the cow" measures that respond after a crime occurs. Attaching an ankle monitor stems from the purpose of tracking the movements of people who have committed specific crimes and preventing reoffending through the psychological pressure placed on them; it is not intended to control offenders' behavior or even the content of their conversations. Therefore, the electronic monitoring system has an inherent limitation in that it is difficult to use it to arrest, in real time, those who plan or carry out actual crimes. Accordingly, to prevent reoffending after an ankle monitor is attached, it is necessary to make probation more substantive than at present by informing the police station or police box with jurisdiction over subjects of the electronic monitoring system of their identity information so that monitored persons are managed at ordinary times as well, and to build a cooperation system among the relevant agencies so that the competent police station can be dispatched immediately when a situation arises in which there is reason to suspect a crime has actually been committed. In addition to monitoring for the purpose of preventing crime, for types that can be classified as crimes involving elements of mental illness, such as sexual crimes, it is also necessary to consider developing reoffending-prevention programs in the form of professional treatment through psychiatrists and others to fundamentally resolve the problems inherent in the offender, and, where necessary, linking them to medical treatment with specialized institutions.

In the main body, the concept and rationale of the electronic monitoring system, as well as its problems and measures for improvement, were examined from multiple angles. The world is in an uproar as heinous crimes such as murder and sexual violence occur day after day. It is said that the increase in crime is nothing new, but in recent crimes the methods are extremely cruel and the purposes of the crimes are unlimited. Moreover, in that the targets are socially vulnerable people such as children and women, or that indiscriminate attacks are made on good citizens who are complete strangers, the public's distrust of and anxiety about the social safety net are growing. If it is impossible to keep even an offender who has committed the most heinous acts confined for life, then realistically that person may someday return to our community and become a neighbor with whom we must live.

For reference, the statistics in the material are figures up to around 2016, so it is better to recheck the latest status with Ministry of Justice statistics. The name of the law was also changed in August 2020 to the Act on the Attachment of Electronic Devices, and at that time electronic monitoring was applied to all parolees and a bail system attaching an electronic device instead of detention was introduced. In 2012 the Constitutional Court viewed the attachment of an electronic device as a security measure rather than a punishment and held retroactive application constitutional, so it is good to organize this in a table together with the human rights issues and the discussion of the principle of proportionality.
