I agree in principle with what you've written here. However, one of the main drivers for a modification (note: not a total abandonment) of the double jeopardy rule is the advances in forensic science - most notably in DNA typing - that can mean that probative evidence does not first become available until many years after the original prosecution.
This appears to have been exactly the case in this particular trial and conviction. [....]
Yes. There will always be specific examples of cases where this change in the law seems to be a good idea. But as I said, hard cases make bad law. This change necessitates the removal of a huge safeguard for the citizen against oppressive behaviour by the state, and it seems intended to be a permanent removal.
The introduction of DNA technology has certainly raised the possibility of acquiring good-quality new evidence from historical cases, over a fairly limited time window. It's understandable that people get agitated about this, and want that evidence used. However, is that really the right thing to do, considering the larger picture?
My first, and lesser concern, is the effect this may have on the thoroughness of case preparation in the future. Let's just try them anyway, on the evidence we have. If it's not sufficient, we can always have another go. Not the sort of criminal justice system I want.
My main concern, however, is the matter I have raised before about the continuing vindictive pursuit of an original suspect, over decades. This is exactly what the law was originally designed to prevent, and I see no evidence that this is less likely to happen now than in the 12th century.
We like to imagine the scenario is one of open-mindedness. A cold case review is initiated, and all the evidence looked at afresh. There is an opportunity to carry out testing not available 15 years ago, and this is done in a spirit of complete open-mindedness. Good gracious, who would have thought it, this evidence incriminates the guy who was acquitted 15 years ago!
In your dreams.
Law enforcement agencies are already talking about re-opening old inquiries, not in a spirit of open-mindedness, but with the specific and explicit intention of finding new evidence against someone they're still miffed was acquitted in the original trial. They're doing it in at least one case where there was no evidence at all against the accused in the original trial, and no rational reason to think any might emerge. It's not about re-examining the case with an open mind, perish the thought, it's about having our original flawed investigation validated.
It's in this situation, the suspect-centred inquiry, that false evidence is especially likely to emerge against the person the police want to convict. I really, really don't think the benefits of being able to get justice in a few historical cases outweigh the serious threats to the rights of citizens inherent in this change in legislation.
