Corroboration - archaic or an essential safeguard?

The Law Society of Scotland is concerned about the Scottish Government's proposal to abolish the requirement for corroboration of evidence in trials. So is Calton. While removal of the requirement would help to prosecute cases of crimes such as sexual abuse of children, it also opens the door to wrongful prosecutions based on the evidence of one person alone and appropriate safeguards need to be put in place before such a fundamental change is implemented. In particular, removal of the need for corroboration could radically change the way policing is carried out in Scotland as there would no longer be a requirement for two officers to provide evidence for a prosecution. That may well be a positive step in terms of cost-savings for our police force however it seems to be a backward step in terms of justice in Calton's opinion.
