Finger prints
For almost a century, fingerprint evidence has been a revered cornerstone of the American criminal justice system. But that may soon change. Last fall, in a Baltimore murder case, a judge ruled that fingerprint analysis is not reliable, which shocked lawyers across the country and could possibly put thousands of criminal investigations in jeopardy. CBS News spent months researching the use of fingerprints in murder trials as well as assessing the future of fingerprint evidence.

Trashing the Truth
"Authorities across the country have lost, mishandled or destroyed tens of thousands of DNA samples since genetic fingerprinting revolutionized crime solving 20 years ago."

Shielded From the Truth
This investigation documented how the Chicago Police Department, civilian investigators and local prosecutors routinely clear officers in shootings before all the witnesses are interviewed, autopsies conducted or basic evidence, including fingerprints and ballistics, analyzed. Over the last decade, not a single on-duty police officer has been charged with shooting a civilian.

Forensics Under the Microscope
This extensive series by reporters at the Chicago Tribune looks at the erroneous forensic evidence used to convict innocent people of vicious crimes. The investigation looks at the unreliability of some areas of forensic science, including DNA testing, fingerprinting, arson theories, and dental comparisons. As a result of the groundbreaking series, two inmates will be released because of faulty forensic analyses and several pending criminal appeals are using the report as evidence.

Science Casts Doubt on FBI Bullet Evidence
This story investigated the validity of a forensics technique, comparative lead bullet analysis, that has been used by the FBI crime laboratory since the late 1960's. FBI scientists determine the trace metal profile of a lead slug and then compare bullet profiles. They found there was not a solid scientific backing for this technique and that new research indicates that the conclusions the FBI examiners drew about relationships between were, at best, unwarranted. There was never evidence to conclude that the fact that two bullets share similar trace element profiles means they are in some way connected, and there is now evidence against that conclusion. This is important because the technique is commonly used in murder cases where traditional ballistics cannot be used and, often where there is little evidence.

Shadow of Doubt
David Junior Brown will soon become the first black man to be executed in North Carolina since the death penalty was reinstated in 1996. He might also be the first innocent man. With no confession, no eyewitnesses, no DNA evidence, no blood, and no fingerprints that place him at the scene of the crime, prosecutors relied entirely on circumstantial evidence to convict Brown of an 18-year-old murder.

The Sciences recommends caution in the use of DNA fingerprinting as evidence to convict criminals; contamination of the sample may taint the evidence; gives detailed scientific explanation of how the "fingerprints," while one of the most promising breakthroughs in forensic technology, are open to misinterpretation, 1989.

New Republic article reports on lawyers and companies using "genetic fingerprinting," in which DNA from human tissue, hair or fluid retrieved from crime scenes is matched with the DNA of the criminal suspect; jurors trust such evidence as virtually irrefutable, but while the method is highly accurate, it is not infallible, April 3, 1989.
