The New York Times calls for prosecutors to establish an "open file" policy to combat prosecutorial misconduct. Here is an excerpt from the editorial:
The Brady problem is in many ways structural. Prosecutors have the task of deciding when a piece of evidence would be helpful to the defense. But since it is their job to believe in the defendant’s guilt, they have little incentive to turn over, say, a single piece of exculpatory evidence when they are sitting on what they see as a mountain of evidence proving guilt. The lack of professional consequences for failing to disclose exculpatory evidence only makes the breach of duty more likely. As Judge Kozinski wrote, “Some prosecutors don’t care about Brady because courts don’t make them care.”
Courts should heed Judge Kozinski’s call, but it will take more than judges to fix the problem. Prosecutors’ offices should adopt a standard “open file” policy, which would involve turning over all exculpatory evidence as a rule, thus reducing the potential for error.
What possible argument could there be against turning over all exculpatory evidence?
