Internet Explorer's "autocomplete" helps convict killer: According to this Boston Globe article, prosecutors were able to disprove spree shooter Michael McDermott's claim that he thought he was travelling through time to kill seven Nazis by examining his computer and showing that he had been performing web searches for "faking mental illness".
