This is a double edge sword because being falsely convicted does not always mean innocent. However, we also know that convictions are the bread and butter of the criminal justice community.
We also know that at both the federal, state and local level, the criminal justice community is not above getting convictions by falsifying or withholding essential information to get a plea bargain or deny defense attorneys essential information that would or could change the dynamics of a case.
At the local level, we have the recent discovery of evidence held in by the sheriff being falsely dated to deny it from defense attorneys. No matter how you slice and dice the data, my sense is that as DNA checks and other organizations start doing the leg work and research we will find that this is only the tip of the ice berg.
Never have I seen written or investigated where those involved in wrongful convictions be it intentional or innocently being held accountable. Yet, there are those that have spent decades and others that have died in prison. Yet, there are those who sleep in expensive houses, hold honors for upholding the law and take Carribean vacations based on manipulating the law.

The numbers are big and getting bigger. As a percentage of the millions of cases, wrongful convictions could be argued to be small but think in terms of 2,000 men and women being wrongfully convicted and then think of the lives of children being disrupted. Bear in mind that in the case of women, there is a 70 percent chance that her kids will go to prison and that each women in prison will average 2.43 kids of whom 50 percent are under the altar of the criminal justice system as a sad and regrettable error. A sad and regrettable error while the system is dinning in Maui or some such place while our jails and prisons continue to fill at tax payers expense.
