The Long Green Mile Revisited: Florida Police Concealed DNA Evidence That Could Exonerate Man Accused In Quadruple Homicide--Does Our Law Enforcement Team Do the Same Just Once in a While to "Win"?

Article reporting the withholding of exculpatory evidence is @ http://www.tallahassee.com/story/news/local/2015/06/12/attorney-fdle-concealed-dna-evidence-quadruple-homicide/71150044/
.
Florida's Department of Law Enforcement sat on DNA evidence for 2 plus years on exculpatory DNA evidence. Motions have been filed to dismiss arguing FDLE’s “conscious, willful and deliberate attempt” to conceal the DNA information [the defendant faces the death penalty].

Until the Supreme Court requires ALL evidence and reports as generated to be simultaneously available for viewing to criminal defendants, this will not stop.

If We Can't Completely Trust Your DA to Toss Meritless Cases, Maybe Some Balance Can be Found in Developing Arrest Integrity Units??

What about developing arrest integrity units in police departments to check, double check, triple check the evidence before forwarding the case to the prosecutors office? If the integrity unit determines there is not enough evidence to bring charges, then the suspect could be released without being indicted. That way the number of false arrests and convictions will drop. Any interest in this locally??

In North Carolina , two innocent men were released on DNA evidence[ http://www.nytimes.com/2014/09/03/us/2-convicted-in-1983-north-carolina-murder-freed-after-dna-tests.html?_r=0] considered by the court over 30 years later. Image a DA's office that would have embraced seeking that justice be done by testing decades sooner?
