I don't disagree, but I am skeptical that they received the same chance as someone without a criminal record. Whether intentional or not there is probably some bias in the hiring process when you know they committed a felony or whatever it may be.

Surely the decision should be based on the likelihood of future criminal action. If a criminal past is accepted as an indicator of future criminal activity then we have rejected the concept of rehabilitation. If this is the only deciding factor we may also blind ourselves to other risks.
