Innocent - but still in the database
Over the last few years it has been common practice to take a DNA sample from persons convicted of certain offenses, and submit it to a national database. The obvious goal is have someone to compare unknown samples. The database has already produced several "cold hits", where previously unknown suspects were identified. Although there have been challenges to collecting the samples, those have not been successful to date, and probably won't be as long as it is limited to persons who have actually been convicted. What if you take samples from everyone who is arrested though? And what if you keep those samples even if the person is exonerated, or charges or never filed. That is the situation that currently exists in Britain and the process is being challenged in the European Court of Human Rights. DNA testing is not the foolproof system it was once thought to be; mistakes do occur, and people have been wrongly identified. How tragic would it be if an innocent person is dragged through the justice system again because of a faulty DNA hit? Let's hope the court does the right thing - otherwise we may be dealing with the issue here.
