Findings indicate that long-term persistent offenders may or may not be high-rate dangerous offenders. Habitual criminality should not be confused with high-rate dangerous criminality. While some existing guidelines for identifying high-rate dangerous offenders are valid and useful, greater accuracy may be obtained through a two-stage screening process. Once a group of high-rate offenders was identified, the subset of high-rate dangerous offenders could be identified using a small number of criteria that include elements of the instant crime. Several factors which are commonly perceived as indicative of high-rate dangerousness in fact proved not to be and, in some cases, were counter-indicators. 1 figure, 3 tables, 19 notes, 13 references, appendix.
