The one time when this argument actually works and I use it I'm accused of being as intelligent as the Daily Mail! A criminal only has to investigate one arbitrary innocent. But the innocent (or the police) would have to sieve through the data of all other people. And someone only becomes an offender when it's to late. There is no guarantee that he/she could be recognized as a potential thread in advance. Therefore certain information should be only provided to people you have reason to trust.
