What is the current state of the law on parole revocation?

It is of course well-settled that, as a matter of law, an individual is constitutionally entitled to due process protections from the moment that he or she is arrested on a suspected parole violation. See Morrissey v. Brewer, 408 U.S. 471, 485, 92 S.Ct. 2593, 33 L.Ed.2d 484 (1972) (In analyzing what [process] is due, we see two important stages in the typical process of parole revocation ... The first stage occurs when the parolee is arrested and detained ... The second occurs when parole is formally revoked.).
