Basic issues relating to sex offender assessment and treatment include possible coercion in obtaining presentence information, the ambiguity or unconstitutionality of certain probation or parole conditions, and whether a defendant must be informed of the collateral consequences (e.g., eligibility for commitment as a sexual predator) or a guilty plea. Incarcerated offenders experience legal issues involving the requirement of treatment programming as a de factor or de jure basis for parole eligibility; a recurrent problem involves insisting on admissions of guilt as a program prerequisite and then using these admissions either for denial of discretionary parole release or, in community settings, for revocation or even as the basis for a new criminal charge. These issues blend into the general area of revocation and the persistent problems related to the Fifth Amendment right against self-incrimination. Appellate court decisions have involved self-incrimination, required submission to a plethysmograph, DNA testing, and the religious foundations of Alcoholics Anonymous. 50 reference notes
