Educating a better class of criminals

One of the things criminology teaches is how to follow a trail of evidence, and education of any sort teaches us to do things which would be useful if we were ever to turn to crime. A criminal merely knows how commit the crime. An educated criminal knows how to get away with it.
Suppose then that a self confessed criminal wanted to study criminology in prison so he would know how to get away with it. Should society pay for his course?
Yes it shoulf. Education makes us all better people, but only some of us better criminals.
