Freedom is not an absolute good; only something that typically advances overall utility, as we understand that people are normally better placed to maximise their utility, being the only ones with knowledge of their desires and values. This, however, is not such a case – as the opposition arguments below suggest, this causes harmful consequences that outweigh any claimed benefits of utility. Furthermore, this area seems to be one where the police are better placed to determine the importance of the information, given their expertise in offending and re-offending , and especially given the tendency on behalf of the public to panic, and place more importance on past convictions than it factually requires.
