of different VNTRs, exponentially increasing probability that a match between two specimens is not an error. Statistically an innocent person would be more likely to win lottery than to be inaccurately convicted using DNA evidence, assuming that proper number of sequences is analyzed.
Where DNA Evidence Stands Now
The first conviction made using DNA evidence occurred in Portland, Oregon in 1987. Juries seemed hesitant at first to accept DNA evidence as conclusive, perhaps because of complicated process - which has been extensively simplified for this article - that lawyers and specialists had to explain to jurors. The process in its infancy left much room for defense attorneys to insert doubt into cases against their clients. However, as science continued to develop, DNA evidence and technology gained a foothold in United States' courts.
DNA evidence and associated technologies were thrust into limelight when a man by name of O.J. Simpson was accused of killing his ex-wife and her associate in 1995. DNA evidence also played a large role in case of disappearance of child beauty queen JonBenet Ramsey.
Just as DNA evidence has been used to convict people of crimes, innocent people wrongly accused have also been freed based on DNA evidence analyzed after fact. Ten people have been freed from death row in United States when DNA technology was finally made available to analyze their cases.
At time of this writing, several states, prisons, and communities are developing programs to create DNA databases, especially from those considered dangerous felons or high risk criminals. The future of DNA evidence in United States lies in hands of legislatures, courts, and responsible DNA labs.
