Police get new DNA powers - crime - national | Stuff.co.nz

Police fingerprinting suspects can now collect their DNA and match it against profiles from unsolved crimes, Justice Minister Simon Power has said. Until now police had to wait until someone was convicted or obtain an order from a High Court judge. The Criminal Investigations (Bodily Samples) Amendment Act means they can take samples on arrest. From today they will be able to take DNA from anyone they intend to charge with an offence punishable by more than seven years' imprisonment. This will see an estimated 4000 more samples taken each year. From the middle of next year if the Government [more...]

National DNA bank for the control of crime is a violation of the ...

One big concern that DNA matching brings up is the spreading practice of “familial searches.” This happens when the police finds DNA material at the scene of a crime that matches the DNA of a known criminal. Then the police starts investigating his or her family members on the grounds that only those within the same family could have such a similar DNA marker. Civil liberties critics argue that this new version of “guilt by association” violates individual rights as well. Five states including Virginia already allow the DNA scanning of people arrested. Even when such people are not [more...]

DNA fingerprinting not exactly reliable in forensics

DNA evidence is not exactly reliable in criminal investigation as interpretation of samples can be highly subjective and prone to error, says a new study.

Defense attorneys had ordered DNA testing but had not yet introduced it into evidence. The tests exonerated the defendant, and the jury acquitted him. In Phoenix, Arizona, jurors in a murder trial alerted the judge that a bloody coat found at the murder scene and introduced as evidence had not been tested for the presence of DNA.

Strange Justice

There is something to forensic science. The Innocence Project has won release of people wrongly convicted of crimes by demonstrating that DNA samples taken at the crime scenes did not match the DNA of the wrongly convicted people. (We see this often in murder and rape cases in which there is a lot of public pressure for police to solve the crimes.) Yet such methods are not confined to the defense. Prosecutors for years have enlisted DNA and other forensic devices to help gain convictions. For example, prosecutors used analysis of wood slivers to help convict Bruno Hauptmann more than 70 years [more...]

Calvin Wayne Cunningham would be the eighth man exonerated by decades-old biological evidence and the third since Virginia began its massive project to clear those who may have been wrongly convicted in the 1970s and 1980s from biological evidence saved before DNA testing was available.

Cat DNA Can Aid in Criminal Investigations | easyDNA Blog

However, cat hair and human hair contain what is known as MtDNA (mitochondrial DNA) and this, like nuclear DNA, is unique to each of us.
