The right to silence spread to many nations of the British Empire. The two different but diverging paths along which these rights evolved and operate in Anglo-American jurisprudence (one through rights expressed in an entrenched constitution, the other in Acts of Parliament specifying rights or protections at common law) can be seen today in Commonwealth nations like New Zealand, where police officers are still required at common law to issue "Miranda-style" warnings (but which are completely unrelated to the US "Miranda" warning ruling) and inform arrested persons that they do not have to answer any questions but that whatever they do say (or do) can be used in court as evidence. The police must also determine whether the arrested persons understand these rights. Any failure to do so can jeopardize a criminal prosecution. While differing slightly from the wording used in the US, the intent is identical and comes from the inherited tradition of law. However, in Australia for instance, anything said by the accused under police questioning while in custody will generally not be accepted into evidence unless it is corroborated, generally by audio or video record. Australian police all wear chest cams as part of their standard issue, and turn them on with every interaction, so that they record and provide such evidence.
