Protective custody is a type of imprisonment (or care) to protect a person from harm, either from outside sources or other prisoners. Many administrators believe the level of violence, or the underlying threat of violence within prisons, is a chief factor causing the need for PC units. This factor was cited by Anderson (1980) and Vantour (1979), with the following broad elements noted as contributing to the problem. Prisoners have the opportunity to request protective custody if they get the impression that the environment they are living in is harmful to their well being. Their request may be granted if the officials rule that the prisoner is truly at risk. Protective custody might simply involve putting the person in a secure prison (if the threat is from the outside), but usually protective custody involves some degree of solitary confinement. For people who are threatened because of their association with a certain group, moving them to another section of the prison may be sufficient.
Early uses of protective custody started in the 1960s law enforcement but it was used infrequently. Federal prosecution of organized crime figures led to the offering of witness protection to key government informers. In 1964 Joseph Valachi became the first La Cosa Nostra member to publicly testify to the existence of the organized crime group, appearing before a congressional committee. Valachi, who was facing the death penalty, agreed to testify in return for personal protection. He was held in solitary confinement for protection and given $15 a month. Since the 1970s the Federal Witness Security Program has grown in size. The program used to fight organized crime, terrorism, gang-related crime, and narcotics trafficking. In 1995, 141 new participants added to the program, increasing the number to 6,580 witnesses and 14,845 total participants since the program began. Also in 1995, 257 protected witnesses testified at trials against organized crime members, resulting in a substantial number of convictions.
In return for assistance from these participants, the witness and family members over eighteen years of age must each sign a memorandum of agreement. The witness must agree to testify and provide information to law enforcement officials. In addition, the person must agree not to commit any crime and to take all necessary steps to avoid detection. Most witnesses remain in the program for two years before pursuing their new lives on their own. Unfortunately these programs were abused by some drug dealers. Some dealers have been allowed to keep their narcotics-generated money and have avoided prison in return for testifying against others involved in drug trafficking.
Witness protection programs also exist in prisons. To protect witnesses serving a prison sentence, the federal government has created witness protection units within federal prisons. Protected witnesses live a more comfortable life than other prisoners, which includes having free and unlimited access to telephone and cable television and the ability to use their own money to buy food, appliances, jewelry, and other items.
