Found this snippet today on wrongful convictions in Canada and how they might happen, bbm;
The Working Group’s recommendations are aimed primarily at the most serious of offences, particularly homicides. These are the cases where the risk of long-term incarceration, and hence the consequences of a wrongful conviction, are the greatest. However, we recognize that some of our suggestions are applicable to other offences as well, when feasible.
Our report focuses on the issues that have been identified time and time again, both in Canada and elsewhere, as the key factors that contribute to wrongful convictions:
•tunnel vision
•mistaken eyewitness identification and testimony
•false confessions
•in-custody informers
•DNA evidence
•forensic evidence and expert testimony
•education
Our report, however, should not be viewed as a beginning or a starting point, but as another stop along a well-established road. As will be obvious, our recommendations build on the extensive work already being done in several Canadian jurisdictions, especially those that have had a commission of inquiry examine one of their prosecutions, which has resulted in a wrongful conviction. We have reproduced many of the excellent policies that have resulted from this work.
The risk of error always exists in any human endeavor. In the justice system, the consequences of a wrongful conviction can be tragic. The Working Group hopes its recommendations, if implemented, will go a long way towards reducing the risk of future wrongful convictions and ensuring that the innocent are acquitted and the guilty convicted.
