Yes, but this is a condition that gets put on sex offenders being released in the community because they can't have a phone that has access to the Internet. Finding yourself a phone that doesn't have Internet capability in this day and age is difficult.
If the breach is deemed to put people at risk.... If you have an offender whose offence cycle is linked to drugs or alcohol and that person breaches by engaging in using drugs and alcohol, then absolutely the judge needs to take that seriously and there needs to be a recourse. In other cases it may be deemed that the breach is not a significant risk.
We want people to not be breaching, to put in place the conditions that support them to remain effectively in the community. We know what does that. We know that programs like Circles of Support and Accountability have all kinds of research to back them up. I've worked with that organization. I've seen it in action. I've had convicted sex offenders in my home.
You ask, “Who would do this?” People do this to ensure public safety.
