In some countries, the authorities publish the names and photographs of convicted criminals on official websites. Although this practice offers some benefits in terms of public safety and deterrence, I believe its disadvantages are more significant, particularly for minor offenders.
Supporters of publication argue that it helps people protect themselves. If residents can see that someone living nearby has been convicted of fraud or violent crime, they may take sensible precautions, such as being cautious about lending money or leaving children unsupervised. Publicity may also act as a deterrent, since many people fear public shame more than a fine. A business owner tempted to cheat customers, for example, might reconsider if a conviction would be visible to anyone searching his name. In addition, openness about who has been convicted can strengthen public confidence that the justice system is working.
However, the drawbacks are considerable. Once information is placed online, it can remain accessible indefinitely, even after an offender has served the sentence and changed their behaviour. This makes it extremely difficult for former offenders to find jobs or housing, and people who are excluded from legitimate work are more likely to return to crime. Publication can also expose offenders and their families to harassment or even violence, and innocent relatives may suffer for crimes they did not commit. Finally, there is a danger that online records are shared without context, so that a person convicted of a minor offence many years ago is treated as a serious threat.
On balance, I believe the disadvantages outweigh the advantages. While there may be a case for informing the public about a small number of dangerous offenders, publishing the details of all convicted people punishes them long after their sentence ends and makes rehabilitation far harder to achieve.
