Here is how OK City handles its problems with DNA evidence in their crime lab and in high profile murder cases that are under appeal. A 2 hour pro prosecutorial soirree was in the judge’s chamber with the DNA lab director and some DAs. Main issue on appeal is the rising theme of DNA transfer onto the victim’s clothing and DNA mixtures. Accompanying this is some crime lab testimony that is considered exaggerated and “out of bounds.” A panel of 25 forensic “friends of the court” got no love from the same judge who petitioned him with their concerns.
The main thread is that the cops ruling the crime lab is a bad deal for justice. But these days justice hasn’t been doing very well. The US Supreme Court just put the 4th Amendment (search and seizure) on life support.
