How long will it be before vigilantes are administering harsh justice to these perpetrators because the criminal justice system cannot or will not protect the public?
I once saw a comment that fell in line with your thinking.
Soon a off-the-books industry that administers post-trial justice for a small fee will have perps demanding to be sent to jail preferably for the maximum time allowed by law.
Picture this: in a bizarre court scene a judge sets a murderer free. The horrified perp demands his lawyer get the finding overturned because the perp knows that once he is on the street, he is a dead man. It seems that the perp found in his holding cell a business card from one of those justice for hire organizations.
