Privatization in criminal justice means that private companies are hired by government agencies to provide services related to criminal justice. For example, private companies might be hired to help with police patrols, process criminal court cases, and provide services related to prisons and jails. When criminal justice services are privatized, it means that the government has given the private company the responsibility of managing the criminal justice system. This can help reduce costs for the government, but it also means that there are fewer government workers and potentially less control over the services being provided.
