Police Questioning (Tape Recordings) 10. Mr. Baldry asked the Secretary of State for the Home Department what evaluations have been undertaken by the police and his Department of the impact of tape recording of police questioning of suspects. Mr. Hurd Field trials to test tape recording equipment and procedures were held in five police force areas between 1984 and 1986. They were continuously monitored and evaluated by the Home Office and a national tape recording field trial steering committee, which included representatives of the judiciary, legal profession and police. A preliminary report was published in November 1984; a follow-up report will be published soon. We will continue to evaluate the effects of tape recording with all interested parties as it becomes widespread. 50.
