Anything that one man can make, another can hack
Granted, it'll be like having an alarm on your home or car: It'll cause the casual criminal to move on to an easier target, but the skilled and/or determined criminal will not be deterred by it at all.
Why can't they just participate in the International space station, again?
Because their xenophobic policies prohibit 'contamination' of their citizens wherever they can manage to avoid it, and besides which they're probably afraid that the crew they send to the ISS would have a perfect opportunity to defect to the West, seeing as how they'd be outside of any countrys' borders while in orbit.
Personally, I'd prefer that convicts serve their full sentences and we dispense with parole altogether.
I think that personally you (and everyone else) would be shocked and angered by how much that would end up costing you in taxes. Prisons are overcrowded enough as it is, and that just makes everything worse, and the problem isn't being made any better by 'operated for profit' privately-owned prisons that contract themselves out to state governments.
If it prevents their parole from being violated
Do you own pets? Ever notice that they learn to not do things you get mad at them for doing (jump on the kitchen counter or on tables, etc) when you're watching, but will do it when (they think) you're not watching? It boggles my mind to think that anyone believes humans to be any different. You watch a parolee 24/7/365, of course they're going to behave, they have no choice. Is that going to really change their character? Maybe not. Hardened criminals are going to wait out their parole so the monitoring device comes off, then go back to their tried-and-true criminal ways. Non-hardened criminals who really want to just do their time and never commit crimes again, live a normal life, may as well have 'CONVICT' tattooed across their foreheads. If you're not going to trust them at all then you may as well just not let them out of prison in the first place. While there needs to be the punishment aspect of the criminal justice system and the prison system, if you're not making an effort to rehabilitate offenders, then what's the point? Some can't be rehabilitated, true, but that's another discussion. For the ones who can and want to be rehabilitated, there needs to be some level of trust or there's not much point in letting them out in the first place.
