There is no debating that forensic science plays an important role in the criminal justice system. One assumes there also would be little debate over the position that, when forensic science is used to convict people of crimes in the United States, that science should be precise and believable.
DNA is widely used as evidence in criminal trials. In Wisconsin and across the country, this DNA evidence can be used in two ways: either to link an individual to a crime, or to prove his or her innocence. While DNA testing can be accurate, there are times when this evidence should be challenged. A man in Wisconsin is currently struggling with this very battle, as he has been accused of a crime that occurred more than 20 years ago. It was alleged that in 1989 he sexually assaulted a 12-year-old girl.
