It's pretty lenient in Canada. Child rapist murderers can apply for day parole in ten years (where yes, they let them scuttle off into society unattended) and permeant parole in 25 years. Families are continually retraumatized every few years in that system by having to beg parole boards to not let out the freak that stalked, kidnapped, raped, killed and dismembered their daughter or mother. They never get to move on.
