Hearing about the man who was released after DNA tests proved he did not commit a murder (see below), i was wonder what makes a life sentance? Does it actually mean life or just until someone is mentally sound or proven innocent by DNA testing? http://www.generalforum.com/other-n...urder-he-did-not-commit-56280.html#post607071 If this man hadn't demanded a DNA test he would have died in prison, and yet another prison is willing to let out the Yorkshire Ripper because he is apparently mentally sound and no threat to women or the community. Both men were sentanced to life, one commited several murders and another lied about commiting one and then was found innocent years later; why is one more leniant than the other? Why were they willing to let out a serial killer and not a man who pleaded his innocence?
