i just worry the law will let paedo scum back into society, and protect their identities.
Funny that. That's exactly what's happening here.
Remember the Dutroux case we had here in the late 90s? His wife let the children die of hunger while he was in prison for some other crime. She claims that she was too scared of him to let the children go and/or disappear herself.
The psychiatrists and the jury determined that she was just as much a psychopath as Dutroux himself, so she was sentenced to 30 years in prison. She served 15 and is now on parole.
In 2001, while in prison awaiting her trial, she inherited an undisclosed sum of money, some furniture and various household items. She officially passed on that inheritance, making her children inherit it instead. That way the victims' families couldn't confiscate it to claim the £150.000-ish she owes them.
The furniture and other belongings conveniently ended up in the monastery where she lives now that she's on parole.
When they released her, there was quite a bit of outrage among the population, so the monastery now gets police protection around the clock.
Justice here is a joke, unfortunately it isn't a funny one.
