Should Confidentiality be Compromised in relation to Rehabilitation?

Ted Bundy, The Manson Family, Aileen Wuornos

These three killers have been over-publicised since their arrests. But publication post-event does  not stop the event happening, or account for the wrong. However, most killers, and indeed most people inclined to commit crime are often known to the authorities before they do anything major. In fact, most people who could benefit from state social care are known to the authorities, but in most cases, help always comes too late. 

Should the authorities, then, share their knowledge with the general public? Would that benefit these people, if everyone could help them or at least be wary of them?

On the one hand, over publicising could alienate people from each other, as  a sense of mistrust and victimisation builds throughout society. As well as this it is compromising privacy. 

But isn't there an argument in favour of free speech here? It is a tricky one as Max Mosely has come to realise, but it also involves the right to know. There is a strong possibility  that society could actually benefit by being more open - I mean look at the Victorians; so secretive and so WRONG! 

If people warned each other, they could also help each other, and trust each other to share. 

Yes in our fast capitolist society the dog-eat-dog business mantra prevails, but I am slowly beginning to think that maybe Aristotle was right, and we should develop ourselves to become more virtuous. And one of the ways we can do this is by sharing...
