public safety vs the criminal justice system

Rather than be issued a public warning from the BC Corrections Branch that a former inmate with violent tendencies and high risk of re-offending is due to be released from jail, how about the Criminal Justice System not release the ticking time bomb or find a new method to curtail any threat to public safety. Case is point, Kayla Bourque, convicted of viscously torturing animals and possessing a murder kit she planned to use on a homeless person or an SFU student. Although not certified psychopathic under the Mental Health Act she is deemed a sexual sadist with no guilt or remorse, and has long been obsessed with inflicting pain on others. Big deal there are 46 court ordered conditions for her three year probation, why is this nut-bag soon to be living in a heavily populated metropolitan area? Why not bring back banishment to a distant land with little hope for survival instead as a legal remedy? Better yet, if there are no family or friends to claim her then she should be marked for destruction.
