There was a useful debate on the government’s desire to reduce the data base for DNA in cases where people have been suspected of involvement in crime. It is a couple of years ago that I suggested a voluntary data base which would be open to all and which I hoped would become a national base when people saw that it did not pose a risk but would offer very real advantages.
The advantages are:
1. Deterrence. A potential rapist or murderer will know that their chances of being caught are greatly increased;
2. Protection against wrongrful conviction. It is a very strong tool to avoid wrongful convictions;
3. It would increase the chance off catching a serious violent offender which in the case of serial killers could save many lives.
I felt the debate did not pay sufficient attention to victims and potential victims. Read on: http://www.publications.parliament.uk/pa/ld201011/ldhansrd/text/111129-0001.htm#11112947000485
