This is not the case in Canada! I'm sure it isn't the case in many other countries too. Here's someone who said 18 times that he didn't want to talk to the police and asserted his right to silence. Appeal denied. Convicted of murder. 2007 Supreme Court of Canada case (R. v. Singh, 2007 SCC 48, http://canlii.org/eliisa/highlight.do?text=interrogation+silence+voluntariness&language=en&searchTitle=Search+all+CanLII+Databases&path=/en/ca/scc/doc/2007/2007scc48/2007scc48.html http://canlii.org/eliisa/highlight.do?text=interrogation+sil...). "Whenever the discussion turned to the incident in question, however, Mr. Singh was less forthcoming. Although he provided some information regarding his presence at the pub on the night of the shooting, he repeatedly denied his involvement and asserted his right to silence. He indicated that he did not want to talk to the police, that he had nothing to say, that he knew nothing about the shooting, or that he wanted to return to his cell. Before Mr. Singh was shown the photographs in question and made the impugned admissions, he asserted his right to silence 18 times. Each time, the interviewing officer would either affirm that Mr. Singh did not have to say anything, or would explain to Mr. Singh that he had a duty or desire to place the evidence before him and he continued the interview."
