I especially appreciate Cohen's treatment of Turner v. Safely, which was as important to corrections as Youngberg v. Romeo was to psychiatric hospitals. Cohen also addresses, head-on, several important dilemmas. For example, an inmate who behaves in an odd and angry manner may be developing a mental illness, aggressing against the prison milieu, or both. Cohen's admonition that "it should not be assumed that this inmate is 'mad' or 'bad'" may seem obvious to clinicians, but it very much needs to be said to judges and lawyers.
