DPS knew eight years ago Moon's conviction dubious

At first, the Texas Department of Public Safety failed to hand over the documents at all in response to the El Paso Times' open records request. When they finally did, it turned out the agency knew eight years ago that Brandon Moon's 1987 rape conviction was possibly false. But when the agency informed El Paso prosecutors of their findings, no one sought further tests that would confirm the false conviction. This quote in particular jumped out at me:

Assistant District Attorney John Davis, who asked Stanley to review the Moon evidence in 1996, said in an interview earlier this year that it "wasn't my role as the prosecutor to go out and manufacture or produce exculpatory evidence."

Yeah, no reason a prosecutor would want to know who the real rapist is, huh? Further evidence why accuracy is optional in modern forensic science.
