> remember the UK also allows adverse inferences to be made from silence, it is not the US
Even in the US, the law has changed rather drastically[0]:
“The only way to prevent the government from introducing evidence of the suspect's silence at trial is to explicitly invoke (assert) the right to say nothing. In other words, without being warned by the police or advised by a lawyer, and without even the benefit of the familiar Miranda warnings (which might trigger an ‘I want to invoke my right to be silent!’), the interviewee must apparently say words to the effect of, ‘I invoke my privilege against self-incrimination.’”
