Objectives of the bill focus on three considerations: the extent to which police should be able to keep a suspect in custody -- legal or de facto -- for the purpose of questioning or carrying out other investigation procedures; the regulation of police questioning of suspects; and rules as to the exclusion of evidence obtained in contravention of laws governing the conduct of investigations. Safeguards to protect the interests of certain minority groups -- Aborigines, non-English speakers, and children -- are recommended. It is concluded that electronic surveillance rights may be granted only under the following conditions: restriction to very serious crimes and in cases where a warrant is granted at the Federal or Supreme Court level. In addition, it is recommended that electronic surveillance be restricted to a maximum of 30 days and be subject to public accountability. Thirty-one references are listed.
