Living with a criminal record can represent a life-sentence to social contempt, specially in the labor aspect, since accepting an ex-convict for a job might be troublesome for employers and could compromise a company/business reputation. These consequences derive directly from the natural judgmental behavior of regular people, and the lack of acceptance as decent members of society can potentially depress these ex-criminals, pushing them back to the only environment they would be warmly welcomed: The criminal life.
Anyone that can disprove further criminal tendencies from these individuals can help them with recommendations to one's own contacts, be it as friend suggestions or employment references.
