28 CFR 524.72 - CIM assignment categories.
CIM cases are classified according to the following assignments:
(a)Witness Security cases. Individuals who agree to cooperate with law enforcement, judicial, or correctional authorities, frequently place their lives or safety in jeopardy by being a witness or intended witness against persons or groups involved in illegal activities. Accordingly, procedures have been developed to help ensure the safety of these individuals. There are two types of Witness Security cases: Department of Justice (authorized by the Attorney General under title V of Public Law 91-452, 84 Stat. 933); and Bureau of Prisons Witness Security cases (authorized by the Assistant Director, Correctional Programs Division).
(b)Threats to government officials. Inmates who have made threats to government officials or who have been identified, in writing, by the United States Secret Service as requiring special surveillance.
(c)Broad publicity. Inmates who have received widespread publicity as a result of their criminal activity or notoriety as public figures.
(d)Disruptive group. Inmates who belong to or are closely affiliated with groups (e.g., prison gangs), which have a history of disrupting operations and security in either state or federal penal (which includes correctional and detention facilities) institutions. This assignment also includes those persons who may require separation from a specific disruptive group.
(e)State prisoners. Inmates, other than Witness Security cases, who have been accepted into the Bureau of Prisons for service of their state sentences. This assignment includes cooperating state witnesses and regular state boarders.
(f)Separation. Inmates who may not be confined in the same institution (unless the institution has the ability to prevent any physical contact between the separatees) with other specified individuals who are presently housed in federal custody or who may come into federal custody in the future. Factors to consider in classifying an individual to this assignment include, but are not limited to, testimony provided by or about an individual (in open court, to a grand jury, etc.), and whether the inmate has exhibited aggressive or intimidating behavior towards other specific individuals, either in the community or within the institution. This assignment also includes those inmates who have provided authorities with information concerning the unauthorized or illegal activities of others. This assignment may also include inmates from whom there is no identifiable threat, but who are to be separated from others at the request of the Federal Judiciary or U.S. Attorneys.
(g)Special supervision. Inmates who require special management attention, but who do not ordinarily warrant assignment in paragraphs (a) through (f) of this section. For example, this assignment may include an inmate with a background in law enforcement or an inmate who has been involved in a hostage situation. Others may include those who are members of a terrorist group with a potential for violence.
