Altering the playing field of Forensic DNA statistics to bring major changes to criminal justice cases


The phrase “don’t mess with Texas” surely is true. The state’s Department of Public Safety Forensic Science Commission’s new stance on crime lab DNA mixture outcomes surely is going to bounce around the county like a flash bang grenade.

More comments from Dallas of opinions that the DNA game may be turning towards a much less robust outcome leaving prosecutors relying more on circumstantial evidence to bolster much weaker assurances that DNA is the “smoking gun” for conviction.

This sea change within the forensic community parallels what happened in Washington DC crime lab where prosecutors and politicians slammed its now ex-crime lab director Max Houck for promoting a similar conservative approach due to subjective and sometimes conflicting DNA examiner’s opinions when mixed blood samples are recovered from a crime scene.
