I advocated for a class action procedure for criminal law similar to civil procedutre due to the travesty of justice the OJ Simpson case presented. If in fact, DNA testing was not conclusive, then that standard should not have been applied to the thousands of cases that preceded OJ’s. The difference was OJ’s $15 million spent upon high powered technical arguments that overwhelmed the LA DA’s office. A class action would pool the best resources of prosecutors and defenses to achieve the most accurate results for all concerned. I see that being justice. What happened in OJ’s case was not justice. He should have been found guilty or it should have placed all the other cases in question.
That's consistent with my post, but My argument is that the reasoning behind DNA testing to determine kinship works at all levels.
An analogy -- not the best, but I haven't had my coffee yet -- would be the integration of the effects of gravity by Newton, whereby he linked the force that causes things to fall with the force that keeps planets in orbit.
