Jury is still out on the effectiveness of electronic monitoring system
Just how effective electronic monitoring is in terms of reducing re-offending is a topic of much debate. Studies carried out in different countries have pointed to varying rates of success.
This is perhaps unsurprising, given that the type of offender being tagged and the period when monitoring is used - be it pre-trial, during early release or at some other point - can vary from country to country.
Successive empirical studies in North America and the UK over the past 15 years had found modest or minimal reductions.
